Thanks for your message here, and thanks for understanding that without some details we can’t really act on people’s comments. We are keen to make changes and now is the time to make those.
Yes, I think with the flexibility that Runbox 7 offers in terms of layout it would be very useful for it to remember how you have the screen set up in terms of what you suggest and also things like column widths etc. It’s been mentioned a few times so I am sure we will do something about that.
The “< >” characters are actually there to indicate you can view the source/code of the email because those characters are used in a lot of programming languages and would be familiar to many people especially those who know HTML. However, now that you’ve mentioned it I see your point, and also some buttons to move between messages would be useful especially if you use a view where an open message means you can’t see the message list (mostly on mobile devices perhaps).
I’ll certainly feed these ideas back to the team, and just for your information you can also create issues for us to look at at https://github.com/runbox/runbox7/issues
We are very keen that Runbox 7 is developed in an open way so that people can see what we are doing. You might also find issues there for other things you’ve noticed and may wish to comment on them.
