It's not present in 1.9b which makes using the new build extremely hard for me

also, the custom images frequently break in size/rotation upon loading in 1.9b which was not present in 1.9

I know it's not impossible to attach objects in 1.9b but I do enjoy being able to move my objects from the sidebar than trying to mess around with wonky hitboxes on transparent objects. They usually load behind the sidebar (on right) so it makes things way more difficult then they should be

Hmm. I'll change the spawn point in the future so they don't load under there. For now, you can prevent that by making the window wider so the sidebar isn't in the way. I'll add the "move" and "reparent" buttons back in for the next version as well so grabbing items isn't required.

Also, items made pre v0.1.9d may be weird when updating since their old rotations and scales were bugged. It should be stable now though, like if you make a new custom item it should be consistent. I did lots of testing, so if you experience something weird I'd appreciate a recording or something so I can figure out what's going wrong.
