Latest spine 1.8.05 on Mac OSX
1) Quitting spine whilst texture packing lets you quit spine whilst still processing and can thus lead to incomplete texture files.
2) Not a bug but might as well put here in spine launcher it says copyright 2013 (its now 2014)
3) When exporting multiple definition (1.0, 0.75, 0.25) images it appears to append -1 to all png files, i would sort of understand if Spine created multi page textures but doesn't from what i can tell.
4) Feature request would it be possible to have a option that puts the files in a folder of the definition name thus all assets will keep same name and can then be put into relevant resolution folders.
