In evaluating the product I've noticed a few "annoyance factors" and just thought I'd annoy y'all with my observations:
Tabbable tabs: Currently the tabs in the dialog boxes are not reachable in dialog tab order. This means I have to pick up the mouse (*gasp*!) to choose a tab.
In the attributes and operations dialogs the "OK" button is not reachable from the keyboard, neither by tab or by hotkey (since "o" is already used by "scope"). (Although to be fair, if all changes are "saved," pressing [ESC] has an equivalent effect.)
While the UI mimics the appearance of VS.NET, keyboard mappings are completely different. Also, while the Toolbox can be reached via Alt+5, there is no way to select via keyboard.
There is no way to select a drawn connector without the mouse. At minimum, the links listed in the Class dialog should be selectable, with the action opening the appropriate dialog.
In general, it would be nice if the only common action that required the mouse was placing/resizing objects on the digrams.
Also, unless I missed something, there is no way to remap a connector. If I have an association with detailed roles and such and I want to point to a different class (for example) I have to delete and rebuilt from scratch.
The colors of class attribute and operation icons in the Project View and class context menu (blue and red, respectively) are the opposite of their text coloration in a class diagram. This is apparently minor, but I find myself constantly selecting the wrong one in the context menu.
If you made it to the bottom of this niggling list, congrats!,
