Works great on desktop 👍

My only request: allow the thread list to be higher than ~40%. If the screen is big, I want to use 2/3 for the list and 1/3 for the message.

Does not work on mobile

Does not work on mobile

thats because of npm link, if you copy /dist from nextcloud-vue to node_modules/@nextcloud/vue in Mail it will work fine. I had the same issue with no-split, and Grigorii mention that its because of npm link

Looks good

After playing around a bit with it a request I would have is some way to be able to close the split, because say I want my full page email list after reading an email (useful for searching). Currently, I don't see any way to do this.

Im not sure if i understand what you mean, if you want to go back to full list of vertical split, you go back to app settings and switch to a different layout.

ah, we have already done the design part of the layouts and the design team wants the buttons only on app settings.

Test on Firefox (v121), seems to work well enough, stops showing on mobile (with nextcloud-vue v8.11), but I assume that's intentional.

Hello, I really appreciate the horizontal split of screen, great work. The whole mail app seems to be perfectly usable in the version 3.6. Only I'd prefer bigger part of mail list (now it is approx. 40%, which is too few). By me it could be from 20% to 80% of screen space - let it on the user whot he/she want to see.
