Can do homescreen icons. It has a widgets “pane”. You don’t place them on the home screen but put all widgets together than swipe to widgets. You can configure kvaesitso so it’s not too different from stock android experience.
I have 5 “favorite” apps at bottom of screen, above the search bar, similar to stock android.
I swipe left for my app drawer, which allows for more pinned favorites above full list.
I swipe up for all my widgets.
Swipe down for notifications, like stock.
Swipe right for my camera app.
No. You don’t manually place apps on homescreen. I have it configured to only show one row of favorites, which are categorized as “pinned - manually sorted”. Than the rest of my favorites are seen when i swipe to app drawer.
