I have tried alot of launchers but never really settled on one that meets all my needs. I have also read all the threads on reddit about FOSS launchers.
My preferences:
Multiple pages
Widgets on home screen
search function; app/contacts/ddg
The closest one yet is NeoLauncher, but the search function is not quite there I reckon.
I missed the question that you were looking for a foss. And I'm not the one posting " it". You've probably missed something yourself, especially if English is not my language.
