That's a very nice looking app - I like the look of it it gives me Mail.app vibes.
A mail client is always a tough thing to get right so I'm glad you're working on one
I love then idea that as the total cost (time/money/attention) of personalizing software continues to come down, more people will be able to encourage a diaspora of options, tailored to each niche.
Visually it resembles Mail.app, but if it’s going for a similar level of functionality I think modern GNOME’s hamburger-and-three-dots-buttons approach to menus is going to become a problem.
This is one of those types of app that really benefits from a proper menubar with several top-level menus so the user isn’t stuck spelunking submenu tunnels.
I'm not anti-AI but I really don't see why they felt the need to stuff an AI chatbox in my emails, other that "because they could".
There’s been a flurry of vibe coded mail apps for Linux in the last couple of months. Hylki is another one. They all look basically the same too.
They will probably all be abandoned within the year.
