Open lots of tabs, start reading them in order, try to close the left most tab > oh, it cannot be done anymore > start reading from the right most tab > close that > tab focus jumps to left most (that now has only speeddial on it), instead of the tab next to it.

There is no flow to it anymore. It should be possible to close the 1st tab, and the tab focus should jump to the tab left of the closed tab (or maybe have a setting for it, move focus to left/right, previously used tab).

Edit: oh, new tab does not open speeddial anymore, it can be only found from 1st tab where it is always open...
