I have to literally take screenshots of my OF screens and send to her so he can do anything with it that she’s tagged in.
Might you use iOS, this can be done much simpler I think. It does require some insight into the URL schemes of OF and Shortcuts.
You describe a very recognizable use case, and what we’ve done is setup “shared” projects, with identical names. So we both have an Inbox of course, we both have have our own projects, but some folders have identical names in our accounts. In fact, the naming scheme is so general, that most of our projects are identical and still allow for personal tasks within them.
We then used Shortcuts to share tasks similar to the maildrop feature, but with a major difference. The tasks we send each other (either through iMessage/Airdrop/Mail etc.) fully contain the details of that task.
So if I want to share a task, I simply press the share sheet, start the Shortcut and automatically send a URL scheme. Pressing the URL scheme on the other device imports that task completely, including all details and notes. And as the projects/folders in both accounts are similar, it will place the task in the same project/folder. No screenshots required.
For us it’s a hassle free way of sharing tasks. When the task is completed we can send each other a “task done” message with another Shortcut. That contains a URL scheme that references the task. As it has a similar name, it’s easy to click the URL, open the task and mark it as checked.
Furthermore: we review our tasks daily, and only discuss the shared projects. You can easily rename the projects with a symbol to recognize them as shared.
If you like, I can explain in more detail how you can use Shortcuts to share tasks in OF.
