I recreated my old tabbed dock with 15 tabs and approximately 200 entries in total. Works like a charm in v2, unusable in v3.
Wow.... that's a lot of entries...
That said, for testing, if you cut that amount in half, is it more responsive? In half again, even more so? The logic is clear here, I want to know at what point, on your PC, where it becomes less and less responsive. Perhaps in the test, there are other things you notice (app types, tab quantity, etc) that could help us here.
Thanks for the feedback.
