@thelittlebrowserthatcould said in Tab Slider:
556 tabs
556 tabs wow O_o! Thanks for telling all the details. The key is Opera Workspaces. I've just tried to open another workspace and immediately faced how Tab Slider slides the tab to the position #2 (instead of #1) in the first workspace, and does not slide tabs in the 2nd workspace.
I've opened this issue: https://github.com/ZitRos/tab-slider/issues/7. I might have some time later to check why it works this way, I have to log how tabs are positioned in "workspaces". Thanks for reporting!
