Officially drop any responsiveness claims and require a minimal monitor width (e.g. 768px or 1024px).
I’m for the second option, personally don’t see much value in having mobile Foreman. Plus it’s not just about Foreman, we need to think about all the plugins we have and their UI.
If we asks users in the survey, we should ask WHY they don’t use mobile version.
If the answer is “I don’t need it”, we can drop mobiles.
But if the answer is “I’d like to but it doesn’t work”, we need to do something with it.
For myself, I would be really happy to have full support for resolutions >= 960px (half of FullHD), so users (including me) can have on 1. half of the screen Foreman and on the 2. half of the screen terminal or any other app.
