Is your feature request related to a problem? Please describe. Many email clients allow me to choose a CC or BCC email address to include when composing emails. For me personally, I always BCC my own email address in, so that my sent email also comes to my inbox. This allows me to track when I get a reply, and also be sure it did actually send as I get real confirmation by the email coming back to me. Describe the solution you'd like A per-account setting to add CC or BCC email addresses of my choosing. Describe alternatives you've considered There are no alternative options within this software. Additional context Example from Thunderbird:

Is your feature request related to a problem? Please describe. A clear and concise description of what the problem is. My mail provider, for some reason, uses folder structure, where "Sent", "Drafts" and "Trash" are listed in "Inbox" folder. Also, mailflow shows another "Inbox" folder, so the structure looks like that: -INBOX -INBOX.INBOX -INBOX.INBOX.Sent -INBOX.INBOX.Drafts -INBOX.INBOX.Trash Other clients shows all the folders on the same level, and my mail provider's webmail shows folders like mailflow, but without INBOX.INBOX Describe the solution you'd like A clear and concise description of what you want to happen. Force default folders to be on the root level, or make such option toggleable. Since I already can hide duplicated INBOX.INBOX folder, that shouldn't be an issue, but if there some way to filter it out, it'll be great. It's quite interesting, that other clients don't inherit this structure Describe alternatives you've considered A clear and concise description of an

Is your feature request related to a problem? Please describe. Right now the only customization you have is basically a color dot for each individual account. That shows through the user interface decently but it could be better. Describe the solution you'd like I'm including a screenshot from the MailBrid production client in Windows 11. It allows for using an icon or even a custom icon to delineate each mailbox along with a color. It just makes more sense and it's easier on the eyes to quickly glance. A lot of times when I just glance at the little blue dot or the little orange dot, I almost think there's a synchronization failure or it's a status update of some kind not necessarily a separate mailbox. IT even looks like an unread mail icon. Describe alternatives you've considered Looked at all other Win 11, Mac OS, and Linux mail clients. Additional context That's it for now. Matt has killer UI/UX skills. Trust his judgement in the implementation. Even Microsoft has a curated emoji

Is your feature request related to a problem? Please describe. Once an email has been snoozed, there is no obvious way to view all currently snoozed messages. This makes it difficult to review, manage, or unsnooze emails before their scheduled return. Describe the solution you'd like Add a dedicated Snoozed view in the sidebar that lists all currently snoozed emails. From this view, users should be able to review, search, unsnooze, or modify the snooze time for individual messages. Describe alternatives you've considered Searching for individual emails is possible if their details are known, but it is not a practical substitute for viewing all snoozed messages in one place. Additional context This would bring snoozed emails in line with other mailbox views and make it easier to manage deferred work without waiting for messages to reappear automatically.
