I almost forgot about those features. I think theyāre pretty solid.
Revision history for me, personally, does a lot. Especially if does exactly what Google Docs does. (Seeing what changes have been made (which are a different color font), undoing revisions, and restoring to select ones, etc.)
Google Calendar, recurring tasks, and true offline mode are something that I could see myself using as well. The main thing with the reminders and calendar integration is that it needs to work reliably (and on mobile, with having persistent notifications (probably Android only) and notifications that donāt go away until youāve read every one (basically generating a new bundle of notifications after one has been read, like Telegram) would be great).
I guess another feature that would be useful is notification pinning, so that way they arenāt dismissed easily. Along with snoozing reminders, I guess.
Support for Googleās Inbox might be useful (by doing things within an email message), but Iām not sure just how yet.
Some people abhor Google, so if thereās a way to integrate CloudKit (and support for Apple Pay, I guess) so that way users could sign up through it, that might be reduce some and pay for itself. I have yet to see someone offer that, of course, so Iām not sure if itās possible/viable/etc.
The search feature that @Yatharth_Agarwal suggested is a good idea.
Extensive settings, perhaps in a section for power users would be good, too.
āSpecial Dynalist Documentsā that are automatically generated, containing reminders, bookmarks, and auto-update as new items are added would be nifty.
Cloned documents would be cool, too. Donāt know if that should be a pro-exclusive feature (and Iād hate to make users who suggested it who arenāt on the pro plan sad), but it could since people can technically link to other bullet points.
Perhaps a cap on how many people can work on a document? That might backfire, though.
