How's the update going? Here are a few of my suggestions:
1/. How about a person for scale as well as the segment for scale?
2/. A button to scale up/down in proportion.
3/. The ability to move / snap the entity to the edge of the segment. For example if you create a false wall, by moving it to one of the edges, they would snap correctly in FPSC.
4/. Separate paths for Import Template, Import Entity and Import Texture.
5/. When saving an entity with the same name as an existing entity, perhaps tell the user that one already exists? and does he wish to save over it?
6/. When saving an entity with the same name as an existing entity, the new version doesn't seem to save as there is one with that name already there.
7/. Pressing Control to move with mouse: I have an entity 3 segments high, I'd like to be able to view the top of the entity to position the texture but releasing control puts the view at the default, which is near the bottom so I can't see the top to position. Perhaps the view could be left where it is when releasing CTRL and perhaps SHIFT+CTRL will place the view back to default?
8/. Mouse scroll wheel to zoom in/out.
9/. Ability to position the texture slowly using the arrow keys to get a better positioning.
Just the odd one or two to chew on
