+# Better Floating Sidebar
+A reimplementation of the floating sidebar seen in the [Floating Compact Sidebar](https://zen-browser.app/mods/46690a54-5eff-4141-8af8-9cd772ab6e2c) extension. Works with gradients and doesn't have the same trigger zone/padding/margin issues as the aforementioned extension.
