I'm using Nova Launcher Prime v4.2.2 on my stock and rooted Android 6.0.1. I intend to create folders in secondary tabs under app drawer. Whenever I create a folder entry through Nova Settings → App & widget drawers → Drawer groups → Folders, the folder gets created only in the primary tab*. Changing the order of tabs under Tabs setting and then creating a new folder doesn't work. The folder always ends up in primary tab.
In the app drawer, attempting to drag the folder minimizes the app drawer and throws user back to home screen with option to place the folder there, just like how an app shortcut is placed.
I noticed an entry for my folder in the table drawer_groups of database launcher.db located at /data/data/com.teslacoilsw.launcher/databases/. Force stopping the launcher, switching the default launcher and making few changes in that table for that folder didn't help either.
So, how do I add a folder into a non-primary tab under app drawer?
* By primary tab I mean the only tab which offers the option to hide apps.
