Thanks Einar, yes we do have that highlighted list when looking at the whole assembly. But when working on an individual part, to me it is not obvious if it is checked out or not. The item is selected and highlighted in the tree (blue), which overrides the checked out color. Hints are [read only] and the tiny blue arrow icon.
Not to mention the tiny blue arrow icon often bugs and does not display correctly unless you click on the row in the EPDM addin-pane.
Good point on making it more obvious Terry. It is nice that you can work on something without having it checked-out, and then realize and check-out without losing your changes. This is not true when you have to change state, and then this can be painful.
Einar I like your edits to the colors, except that....
*The "Referencing File Version that is Not the Latest" doesn't seem that important in this context since it will be fixed if you save and check-in the assembly. We turned off the rebuild warning too because it is just too ubiquitous.
* "file is edited but not saved" seems mostly worthless since it will light up even for things that are checked-in and not intended to be changed.
