Great except for autohide/shrink Rated 4 out of 5 stars
Problems & suggestions:
1) After autohide, when I hold Ctrl to show the tab bar, all the children tabs slides rightward, shortly after the tab bar's appearance. It's because the ends of long titles are replaced with '...'. The sliding is subtle but very distracting. If you can remove the sliding by disabling the replacement with '...' or by other means, it will be great.
2) The sliding doesn't happen with autoshrink, but because the tab bar is translucent, expanded tab bar will have a high-contrast line crossing it vertically in the middle, making the titles hard to read. I wouldn't mind losing sight of the left end of the page temporarily for aesthetics & clarity. (Note that in case of autohide, such high-contrast vertical line doesn't exist, and translucency doesn't harm clarity of titles)
Since autohide or autoshrink can provide laptop users like me with much-wanted space, I think the above issues are important. Thank you so much for the otherwise excellent add-on, and I'll be looking forward to an update!
