I have been looking for a (very) long time now for a good todo list, I even wrote my own program(s) before. (gtodo, gtodo2 and more).

I used google tasks for a while, but it has no decent desktop client (that does offline) and not a google written android application. I tried any-do (but it had sync issues), todledoo,

I tried a text file in my Dropbox, but having it open on mulitple pc’s caused issues, Git repository is not useful on my phone/tablet.

So latest version is an imap mailbox for ToDo’s.

I will let people know how this goes, beside alarms (that I never use)  and priority it seems ok..

Priority I can use labels (though my android client does not support it).
