Just as it says: after some use, you will find it cumbersome when tabs don't reorder when you open them, even in spreadsheets! Which is good. I only wish there was an easy way (not having to go to the "Manage extension" page) to disable it temporarily, for example, when you want to dig through your older tabs (that is, the ones more to the right) while keeping them close to each other. Otherwise, this is perfection

This addon does what the description says, and it's really handy when I have too many tabs open.
