For instance, a button can be implemented simply with an optional caption. Usually you want the caption to be centered, but I ended up using the button control for other things as well, and ended up wanting the text left justified at times.
Also, for checkbox type items, it's nice to do justified text, so the option is forced left, and the check mark is forced right, which is not otherwise simple with proportional text.
So, you end up adding text formatting options to most things that can have a caption.
The main progress yesterday was getting the entity tab up & running again. You can do basic ops on existing entities with just buttons, but now I have a scrolling button box for choosing which category, then entity type to create fresh.
Below it is the facet list, which lists the entity's properties, but in a few hours will allow you to edit them as well, and add new ones.
