And another iteration:
Is it me, or is the mail-archive not showing all mails in a timely manner? It
took two days for one of mine to show up.

Yes, that's why there's a drop-down there. If you want to choose a tiling type
immediately, then you use the drop-down. Also, the tile type can only be
changed in tile edit mode. Users probably won't spend a lot of time in that

The tiles behave like objects, so you can transform them with the F1 transform
tool, and you can snap them to other guides.
For radial and line tiling guides, you can also input numerical values
in tile edit mode. I'm not sure what to do with the wallpaper tile though, since
there are so many different shapes. A possibility is to define the coordinate
of the first center of rotation + the length of 2 sides (only one is used if
all sides are equal length).
Now to answer Jasper:

Ah yes, I noticed the hard way that P2 tilings behaved weirdly... (i.e. I
was trying to understand what it does by actually trying to render it)

But the base tile is still the most intuitive guidelines one has for wallpaper
tilings... Also, you need to know where the edges are to create seamless
Or do you mean that the extra stuff gets in the way? The handles
etc. aren't visible outside tile edit mode. Since the default tile is a simple
P1 tile, and you need to bother double-clicking the tile to enter the
edit mode and change what it does, I think we can assume that the
user won't be too surprised if the output is no longer a simple P1.

Huh? It's still the same tile, just flipped. That's how wallpaper tilings work.

I'm not sure what interface you're proposing. I know nothing about tilings,
and the only thing I care about for tiling is that when I click the "apply"
button, I get a pretty result (and a seamless output would qualify for the
"pretty" factor). The specific transformations don't actually matter at all
to users like me. :S
