    I tested Stellarium 0.11.2 recently. I am not an astronomer.

    Here some remarks, which I want to tell you.

    1.) If I switch off the atmosphere (A on Keybord), then the fog above
    the horizon of the landscape is still visible.
    When only working with the toolbar buttons (as beginners do), this is
    disturbing. (Beginners do not know the F key.)
    Please correct this - primarily with the toolbar button.

    2.) On Microsoft Windows 7, working in fullscreen mode is troublesome, as
    the cursor disappers after some actions.
    If not in fullscreen mode, you can work properly on Windows 7.
    But Stellarium is started in fullscreen mode on all operating systems.
    I suggest to start Stellarium in Windows 7 in normal mode as a first remedy.
    Then people who only want to see a simulation of the sky are not embarrased.
    '"C:\Program Files (x86)\stellarium\stellarium.exe" --full-screen=no'
    in a link can do.

    3.) I wanted to see some double stars. I tested Rigil Kent. It was not easy to
    separate the two components, as they are too large on display.
    When increasing the year, they do not show to turn around each other.
    But Stellarium shows them drifting away from each other in 2000 years.
    A similar effect can be seen with Epsilon Lyrae.
    From this, I assume, Stellarium does not show periodicity of doubles at the
    moment. This should be mentioned in the manual.
    Also the change in magnitude with varible stars (Algol) cannot to be seen.

    4.) For some special observations, it would be helpfull do reduce the shown
    diameter of a star, which is used to simulate the magnitude of a star.
    (The diameter of a star shown in a telescope is a parameter of its aperture.)
    Regil Kent could be better displayed as a double star if the displayed
    diameters would be smaller.
    As a first remedy there could be a button on the toolbar for this, which
    perhaps toggles config parameter flag_point_star.

    5.) If you click a star with the mouse, you get some information about it.
    Stellarium should display all available information - also the angular
    velocities dx0, dx1 from the star catalogue files where available.

    6.) Please give the clicking on a star a higher priority than the clicking on
    a nebula. Often it is nearly impossible to get the information about a planet
    or a star. If you click it, you nearly always get the information on a
    nebula behind it or near by.
    I always switch off the display of nebulae to avoid this behaviour.

    7.) It is a common problem with Unix, that the texts and buttons in a dialog
    box are too far apart. As space is a high-valued resource on the screen,
    all the dialogue windows of Stellarium should be reduced in space.
    MS Windows is by far better in this behaviour - concerning dialogue windows
    here only.

    8.) I had some problems with the search window. I could not find Toliman,
    which is a often used name for Rigil Kent. I had also proplems finding
    Japetus - in Stellarium it is written Iapetus. Phoebe is not shown at all.
    What about Sirius B and Sirius C ?

    9.) When observing the movements of moons, I chose the north pole of sun
    as my observation point, as on earth the orbits are not visible as ellipses.
    I saw a considerable wobble on the small moons of Neptun when displayed.
    If I watch Thalassa for example, I see a solid circle with a second circle
    wobbling around it. This second circle is a bit larger and has a nebular
    fuzzy edge.

    10.) For auto-zooming a selected object, you have to use the key /. On some
    keyboards this key is not easy to be used. On the German keyboard it is
    "shift 7"; \ is "AltGr ß" on this keyboard.
    I think double-clicking the selected object is a good alternative.
    To zoom out, double-clicking with the right mouse button would be an
    alternative; the backspace key could also be used (browsers behave like this).

    11.) The rings of Uranus, Neptun cannot be seen on Linux and Stellarium
    0.11.0.

    1. The fog can be removed by unticking show fog in the landscape menu

    2. This is a user preference that can be set as required in the config.ini file

    3. Stellarium uses the standard informarion regarding star movement over time and can only display these results.
      The manual is not current and you could enter a suggestion to be included at a
      later date.

    4. The size of the displayed stars can be adjusted to suit what you prefer by scrolling the absolute scale and relative scale in the main menu.

    5. clicking on the star gives all the available information in the catalogue however some early versions of Stellarium did not display everything.

    6. This is a limitation of display size to select a star that is covered by a nebula it may be necessary to turn off the nebula as stated.

    7. This is just the way the programmers like it.. If you have a better method inclide it in a suggestion list

    8. All the possible names for searching are not included in the data bases. However you can add any names that you prefer in the star_names.fab , NGC2000names.dat. etc These files are all ASCII and can be edited.

    9. This is probably due to the orbital information of these moons that has been included in stellarium. If you have any better information please let us know.

    10. Hot Key alocation on non US keyboards is a problem we are working on to overcome.

    11, The texture for Uranus and neptune moons is an addition made with version
    0.11.2 and is not available in 0.11.0

    Stellarium is not able to display everything to a users liking "out of the
    box" but there are inbuilt features to modify the display to suit just about
    everything you have mentioned. If there is any other things you would like to
    see there is a suggestion list available via the wiki.
