Hi - I've sent some notes via text, but I wanted to suggest a slightly different implementation for how Airmail handles To-Do items (and how it integrates with Gmails tags as a result). The current implementation makes it very difficult (and I think, for me, impossible) to create a consistent GTD implementation within Airmail (which was the use case I was so excited about). But I think one small change makes everything work (and may make some other features easier as well).

Essentially the changes are these:

1. Whenever an email DOESN'T have an Airmail-Done tag, it appears everywhere. Whenever it DOES, it doesn't appear anywhere (unless something like a menu option of "Show Done" is selected).

1. Marking an email as DONE only applies the DONE tag - and changes nothing else about the email.

That's it. It really raises "TO-DO" and "Done" to a more canonical state within the app, but I think also simplifies the implementation.

That one change allows the following which currently you can't do:

1. Mark a mail with multiple labels "Done" and have it disappear from all labels (right now if I have an email labeled "Waiting For" and "@Bob" and I am in my "@Bob" folder and mark it as Done, it still appears in "Waiting For"

2. There is no way for me to track back through things marked Done sensibly to see where I had filed them (in the above scenario, it also removes my "@Bob" label - which means I can never again see I had been waiting on Bob for that item).

It also makes my GTD system very inconsistent - as when I mark items as "Done" - they still appear in multiple other places, which gets very confusing to track.

I am happy to talk about this further if helpful, but I am very much begging for this slight change in implementation (or at least to know if you will consider it) because without it I probably need to switch to another email client or at least another tool to manage my work (which would make me sad as I really like Airmail :) ).

Thanks!
