Some filters in the animation selector screen have been turned into combo boxes so you can see what the used values are.
The row-expanding arrows at the far left of the timeline are now bigger and easier to click.
If the mouse is in the canvas, using the mouse wheel will zoom the selected particle in/out. Holding Ctrl does NOT currently work to make the zooming faster because of a bug in mkxp-z. Zooming this way doesn't keep the particle in the same aspect ratio if its X and Y zoom values are different.
Right-clicking anywhere in the canvas and dragging will rotate the selected particle.
Pressing Tab or Shift-Tab will select the next/previous particle respectively.
Fixed some bugs, added Polar emitter type (lets you move things in circle/pretzel shapes or along a radius, or both), tweaked Helix emitter type, added emitter parameters to randomise the zoom (x/y/both) of emitted sprites.
Faster movement of something in the canvas (with WASD) or the selected row/keyframe in the timeline (with left/right/up/down) now happens when holding Ctrl rather than Shift. Fixed visual error when undoing/redoing.
