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