Expanding upon the idea of a .ini token... depending on how many dialogs this could affect (say, 5 or less), each could have its own .ini token. If more dialogs are affected, they could all share one token and it could be an unsigned integer where the integer holds information on whether a certain dialog should be displayed or not. For example, say the token value is 56. That's 111000 in binary. That could represent windows 1, 2, and 3 should not be displayed (the lower 3 bits) and windows 4, 5, and 6 should be displayed. There could also be an entry into the Tools->Settings dialog where users can select which dialogs are displayed (along with a "Show All" and "Show None" button that selects/deselects all).
While this is a great idea, it isn't within the scope of the topic. I was originally looking for dialogs that need to be reworded.
The .ini token idea though is a great idea! I think it should be submitted to the idea exchange and see how other users feel about it.
