I often hit the limit of 3 open draft emails in Proton Mail. This is really annoying. You're working on different emails and a new email comes in, you need to respond, and you can't! Until you close one of your existing open drafts. This is horrible UI, horrible usability. We need to be able to edit at least 5 at once (preferably no limit at all).

Thanks for all that you've already done to make Proton Mail pretty good, it's appreciated.
