The cool thing about Howm is that it's note-taking and task management for lazy people. It predates org-mode (but it also works with it nowadays) and has a distinct way of linking notes by way of go-to and come-from links, think saved search and automatic backlink respectively. Also the way tasks are displayed and surfaced is pretty neat too, the guide/manual goes more in-depth but if you find stuff like org-agenda too complex you'll appreciate Howm's way of tracking and managing tasks.
These days I use niri which at its core, is just Alt-Tab blown up as your actual desktop.
Though you'll have to fiddle a bit with stuff like waybar, fuzzel and xwayland-satellite. But once you've configured that stuff you won't have to fiddle with it non-stop.
I'm currently running it on Fedora, to be clear.
