I have tried: Powertoys Run (PTR) and the newer Powertoys Command Palette (PTCP)as well as Flow Launcher (FL). Flow has some plugins I wanted, like a OneNote navigator. I am running out of keyboard shortcuts to launch these tools! At the moment I favour PTCP for “windows walking” and FL for navigating OneNote pages that aren’t open.
