Currently scrolling past the last task activates the first one, and scrolling past the first task activates the last one. I found this behavior to be more difficult on a laptop's touch pad. When I'd like to go to the first/last task, I wouldn't have to pay attention to not "overscroll". Other than that, I can't think of a strong use case, except for it being a personal preference. It's really just a neat feature to have, and nothing absolutely necessary.
Sounds very reasonable to me. I wonder if this should maybe just be the default behavior - tab bars in e.g. dolphin and kate also do not wrap around. ... I just checked whether there are people complaining that tab bars don't wrap around, and found that this issue was already reported a couple of years ago. And in that bug's thread, Nate Graham made the exact same argument, that it should just be the default behavior. Good job making a case for this and splitting it out from the mixed report. I'll have to close this as a dupe anyway, so that we can keep things as clean as possible here. Let's hope a developer takes an interest in this, it probably wouldn't be too hard to implement. *** This bug has been marked as a duplicate of bug 404781 ***
