LB TAB Layers is a Chrome side-panel extension for managing tabs. A mode bar at the top switches between five modes — Tabs, Clean, Shots, AI and DB (dashboard). At its core is the Tabs mode: you gather tabs into groups, and every group is saved as a real Chrome bookmark folder, so your data stays even if you remove the extension.
In the tables below, Free means the feature works in the free version. PRO means it is part of the PRO version — and every PRO feature is unlocked during the 3-month free trial.
