I moved from Niagara to Kvaesitso - my subscription lapsed and there were no Google Play free credits available to renew it. The renewal price was silly anyway, was almost triple the previous amount.
Kvaesitso is quite different but like it generally. Only thing I miss is the contextual calendar events shown under the clock - the equivalent space in Kvaesitso currently shows either the date, time until your next alarm, or some other misc stuff, so hopefully shouldn’t be too difficult for a dev/contributor to implement contextual calendar events if they choose.
The search is much more capable than the one in Niagara. You can optionally tag your apps too, so if you search “nfc”, all your NFC apps show up, or “sysadmin” to show all your sysadmin/homelab apps etc.
I’ve customized mine quite a bit so it looks very different from stock, home screen is also much emptier than it was before. Took almost an entire day to get it just right for me
