Hi,
I’d like to mention another Revo part that is baffling my tech-savvy clients. MODx Resource Browser
In the MODx Resource Browser, [In English: the thing that you use to upload files, make file folders, stuff like that] the Upload window (which you can find once you look around for awhile and come across its tiny icon) is, well, not very forthcoming, let’s say, it’s chiefly blank. You have the funny "Waiting".... OK.

And yes, I managed to stare for awhile, and finally found that I had to use the little "Add" button. My clients, who are very experienced web developers, did not find that, and had to ask me for help.
Sorry I keep dinging you guys on usability.

Gee, maybe just having bigger icons for those functions will help, if you folks don’t want to label them (yes, I know you can get tiny words if you hover).
Cheers
