NEW: UNDO and slider-under feature

[Markus W]

We have some really cool (and really long overdue!) features now:

== UNDO ==


It is now possible to click the "UNDO" button to undo your last move. This even works for multi-moves - in this case pressing undo will revert to how the tiles were before you selected them.

== Slide under ==

If you hold down the CONTROL key (Mac users: use Apple/command key) when you release a single tile, it will slide under any other tiles.


This is very useful for fine work, for example around edges, and of course if you just want to hide excess tiles.

NOTE: Pressing CONTROL when you pick up a tile has a entirely different function: This will copy the angle of the last used tile to the current tile - also a very useful function to create lines of tiles at an angle.

However, if you want to use the slide under feature, remember to use the control key only as you RELEASE the tile.

Update: The slider-under feature appears to be quite buggy at this point in time. Please wait with your bug reports for 24 hours to give us a chance to fix the most obvious problems.

== Undo feature ==

Just a quick tip: Instead of the pressing the UNDO button, you can also press "z" on the keyboard (I suppose control-z would work too).

== Slide under feature ==

In regards to the "buggy" slide-under feature, it's actually working but can produce unwelcome effects:

Currently, if you're moving a tile under other tiles, the tiles affected will actually be placed on top of the tile you want to "hide". Of course, if *these* tiles were half covered under other tiles, they will end up on top of these tiles.

The only solution is to bite the bullet and calculcate all overlapping tiles of the overlapping tiles and so on, to make sure the relative order of the tiles in terms of their z-index is not disturbed.

Rest assured we're working on this and should have it working exactly as expected very soon.

== Copy last tile's rotation using shift-click ==

Copying the angle of the previously moved tile used to work using control-click. This had caused some problems because the slide-under feature was also using the control key, but control-release.

We've now changed it so that control-click is basically moving a tile to the bottom immediately.

"Copy tile rotation" is now done using shift-click, and shift-release is still tile snapping (which still only makes sense with unrotated tiles).
