The best launcher/spotlight replacement I've ever used. Incredibly polished and capable. I wish this was available on Windows as well but it's not looking likely to happen. The closest you will find is Flow Launcher which is incredible in its own right and at least it's open source.

Very solid PKMS with infinite outlining as a central mode of writing. FOSS project with a vibrant and fun community. It's easy to jump in and make contributions. Think of some way you could improve the product? You can write custom Javascript that gives you the full capabilities of their plugin api. I highly rate this PKMS. It's an exemplar of the power of FOSS
