Bookmarks Bar Switcher for Chrome
More About Bookmarks Bar Switcher
How to use:
To start, name your current book bar.
To create a bookmarks bar that you can switch to, create a folder within Other Bookmarks.
How it works:
When switching, your current bookmarks bar will be backed up to a folder within Other Bookmarks with the name you initially specified.
And the folder you selected will become the new bookmarks bar.
So any changes you made on your bookmarks bar will stay when you switch back.
It doesn't work well across multiple devices.
Reports of bookmarks mixed up have been received.
It's probably something to do with the chrome bookmark sync functionality.
It's very likely to happen when you switch the bookmarks bar while chrome is syncing the bookmarks.
At the moment, there isn't a good way to fix the issue. Because chrome doesn't provide APIs to tell when the sync starts or ends.
But one way to potentially avoid the problem is when you switch device, don't immediately switch the bookmarks bar. Give it sometime (2-3 mins) to finish the sync and then switch.
