Widget for Quick Notes still missing

This app is my daily companion. Simply great. However I still wait for the widget as shown in the tutorial.

Best mindmapping and thinking app. Period

I put my life in this app, my filing system and my pkm system.

Gardening your brain is a thing, it’s a daily habit - use this app to log and document; it works the way my brain does.

Mostly use on mac (bought a new m4 iMac, mainly for The Brain) on mobile it’s very good - near parity of features, but it is best on a big screen (iPad pro 13 is good too)

Have used this as a pro user since v4. Now we are v15 and it’s brilliant and fast. Just gets better and better.

Prefer this over obsidian and other pkm apps (have tried them all).
