This is a not-perfect concept of how tabs can be implemented on the drawer.
The idea:
there is the main tab āAllā with her pill that will be shown only if thereās at least one additional tab. We could insert 4 tabs so we can see 5 pills (āAllā pill included) because the grid of the drawer has 5 columns, every pill shrinks the āAllā pill. When you click on a pill it grows and the āAllā pill shrinks.
We can add tabs from 3dot on the search bar, and we will see the option āAdd tabā. Long-press on the pill that was created shows the option āRemove *tab name*ā. The tabs can have a custom name, and it will be renamed long-press on its pill and select the option āRenameā.
For adding an app to a tab we can long-press on the app and the option āMove toā will allow us to choose the desired tab. On the custom tab, long-press on the app will show the option āRemove from *tab nameā
Hope this idea is appreciate
