Just made an observation, regarding the editing screen, and the URL Attachment pop-up.
In the old Jive, the cursor automatically positioned in the editing screen, ready to enter text (an improvement from much older forum software, where one had to click in the editing box), but if one mis-typed text, and deleted all of it, the cursor disappeared, and one had to click back in the editing box. I just did that, expecting to have to click again to get the cursor - but in the new Jive, it was still there, though I had deleted everything. I like that.
Also, with the URL Attachment, when the pop-up dialog box cycles through, the "http:" is already highlighted. As I most often have done a Ctrl+C of the desired URL, I already have that. IIRC, in the old Jive, one had to click-drag over that "http:" so that the full URL would replace it. I like that.
While minor, they save me clicks, and moments, and that can add up on a busy day.
Bound to be some more "improvements," that I have just not encountered yet.
Thought that I would add some "good things," as most recent posts have been about undesirable behaviors.
During beta, there were things that we could not (or perhaps, I did not) explore, but in general, I am pleased. For most of the rest, I am sure that someone here will teach me how to do it properly. Heck, up to the last few months of the old Jive, I was sitll learning things from some of the folk here, and I had used that software almost every day from roll-out.
