Great add-on, but a Bug is really anoying me since late 2021. If I close & reopen the browser, every tab in groups with "always open tab in specific container" option activated is duplicated (see here: https://github.com/Drive4ik/simple-tab-groups/issues/891 ). The issue is open since Dec, 2nd and the developer didn't answered (we are in February...). Update: going from 2 to 1 star to see if the developer only cares about 1 star reviews....
