After creating a new mail and leave it minimized or under another window, it appears some moments after in the Drafts folder with a bold typeface as usual. That’s OK
What I find anoying is the fact that if I double click on the mail on that folder to conitnue its edition, another copy is built up. Now I have two (possibly there can be more) copies of the same drat. So If I send this last copy, the minimized one continues alive and if I “recover it” minutes later, I don’t know if I have sent it or I have to finish it. That’s truly a mess.
I think that when a draft is recalled, if there is an already open mail form linked to it, the same mail form shoud be used, not a new one.
