More stuff for the pile:
1.
This is an old problem but still present in the EE Editor. The icon previews do not load in the editor without extracting data from the icons.pak and placing them in the folder: Data\Public\Shared\Assets\Textures\Icons
The files are pretty darn small so perhaps you could just include pre-extracted versions in that location?

2. When placing objects, if you immediately hit undo you get a message that says "Blocked by source control".
The object does disappear but it moves to the 0 location of the level. It will disappear upon restart however and cause no problems.
Improvement suggestions:
1. The line of sight fade out of NPCs while in editor mode is quite annoying. The old version didn't do this.
2. Include Alignment.lsx
Data\Mods\YOUR MOD\Story\Alignments
Along the same lines of usability, it would probably be a good idea to automatically make a copy of the main alignment folder/file everytime a new mod is created. Anyone interested in customizing would figure it out but a newbie will have a much easier time if it's already there.
