Tab Slider

@zitro: "Cycle tabs in most recently used order" is now disabled, but hasn't fixed the problem. I don't use pinned tabs. I also disabled tab scrolling, to allow me to more quickly to return to the tab position where the problem arises in a workspace with many open tabs, but that, also, didn't fix it.
So, the problem varies between Opera's workspaces: for one it may affect all tabs to the right of the 19th tab from the left; for another workspace it could be the 70th tab. During a session, this behaviour appears to be consistent.
Recent improvements in tab snoozing etc mean I can have about 50% free RAM with over 500 tabs, but there wasn't a problem with Tab Slider (which I've been using for over two years) until the last few days and, I think, this update to Opera beta.

@thelittlebrowserthatcould thanks for the details. If only could I reproduce the problem... However I didn't get what actually happens or doesn't work? Is the tab not sliding to the left when 70+ tabs are open? Is it sliding to the left but not to the very left position (slides to position #5 for instance instead of #1)? Doesn't slide at all?

Also, are you switching tabs with a mouse or a keyboard?

@zitro: Right now I have 556 tabs (most are snoozing) spread across 12 workspaces. This sort of load has never been a problem in the past two years for Tab Slider. I usually mouseclick on a tab, or open a link in a new tab, to get Tab Slider's expected behaviour (move to leftmost position after 1 second delay). Currently, the affected tabs do not slide at all, and the positions of the affected tabs appears to be consistent between browsing sessions. In my current session I have one workspace of 51 tabs where Tab Slider does not work at all (for any tabs); another with 14 tabs where Tab Slider works for only the first 6 tabs counting from the left; and another where Tab Slider works for the first 72 from a total of 116 tabs. Using the "2" key to travel across from position #1 to a tab to see whether it is affected is no different to using the mouse to select the tab (provided the tab can be reached quickly enough using the keyboard, if it is in my setup's effective range for Tab Slider with the workspace in question).

@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!

@zitro: I've been using Opera Stable, with no problems, until the recent update to 97.0.4719.26, which also affects the Most Recent Used Tab Stack extension, from the Chrome store.
