@Mtt So for the delayed response. The only other suggestion that I have is Calendar 366. For me it enriches Apple's Calendar app while bringing in Reminders alongside. It's available for Mac and iOS.
I am not a huge Reminders user, though at times wonder if I should give it a better go. I use Wipr and make sue of Shortcuts to save notes...though not to Apple Notes, but iA Writer. Given how much I use Apple Notes, perhaps looking into some Shortcuts to automate that process would be helpful?
I tried ShareShot, but while I liked the app, I don't make a big use of screenshots to share.
