You can now "pin" your tabs on the row of TooManyTabs and they would stay there unless you "unpin" them (all via the context menu). When you click on a pinned tab, a new instance of that tab opens and the pinned tab will remain on the row. Definitely the best way to keep your favorite sites within reach!
There are more advanced tricks that the pinned tabs can do! Say, to keep a group of frequently visited tabs, select a new row on TooManyTabs, pop up multuple tabs to the row, then open the context menu and choose "Pin All Tabs in Row". When you need the group, you can open them all at once. (via context menu > "Open All Tabs in Row"). To improve tab navigation, we also implemented the open-new-tab-adjacent-to-selected-tab feature. You can toggle this option easily in TooManyTabs options menu. When you open a new tab or restore a tab from TooManyTabs, the tab will open next to your current tab.
TooManyTabs is also now compatible with tab-related add-ons like tabkit, colorful tabs etc. Thank you for supporting TooManyTabs!
