I should have added that keystroke equivalents give both 
   ease of learning for the beginner via the menus, and 
   good (perhaps the best possible) facile and fine-tuned control for the experienced users and astronomers.

PS:  Just updated my notes at takken.us/stellarium.  Hopefully they are more readable now.


Hi Tom,
It is the keystroke equivalents that are magic.
The menus after a while are just a help display.
Sub-menus can be used to make things fit on a small display.

Hi Ed,

I'm not convinced that replacing the nebula sliders with a drop-down
menu would be more intuitive although I'm no expert on GUI design.
Bear in mind that non-numerical information needs translations unless
you use icons, potentially causing layout problems. Also drop-down
menus wouldn't fit on a small screen (e.g. smartphone).

Thanks,
Thomas

Hi Thomas and Brian,

I think the way to do this one, as well as make the user interface both more
facile and intuitive, is with drop-down menus.
I put a draft of my idea at  takken.us/stellarium, but need to do more to
explain it.
I suggest that the present slide bars are an encumbrance for the user.

Hi Brian,

Perhaps this could be implemented as a plug-in? ("extended DSO
controls" or something like that). Personally I would like some
extended controls particularly for making full use of the new NGC data
catalogue. (Galaxy display based on surface brightness for example,
which would certainly be useful for objects at low altitude.)

Thanks,
Thomas

Cool!


I have a prototype image here:

Oh, my, more interface clutter. While users have requested a way to

select which categories of DSOs are displayed, I think that a separate

slider for each is overkill.


Also, a comment on a previous question of yours:

I also think that the sliders should be ticked and a label show their

current value, because I'm not even sure what their value currently

represents. (I assume apparent magnitude)


The sliders are deliberately unitless and don't represent apparent

magnitude. Instead, they control the number of objects shown on the

screen with a somewhat unclear formula which includes apparent

magnitude and dynamic eye adaptation.


Please also have in mind that one of the reasons Stellarium is popular

with educators and people who are total beginners in astronomy is the

simplicity of its interface. New features should be carefully

designed. Just slapping hack over hack as has been the tendency

recently won't lead to anything good. We already kicked out the

planetarium users, let's not alienate more groups.
