Hi Sven, thanks for reaching out :)
Currently, it's not possible to modify the width or appearance of the menus. I've swept through our portal and I couldn't find any request for such feature, so maybe you'd be interested in submitting it yourself. You can do so via this portal.
After you submit it, it could be a good idea to share the link here so other people interested in the same feature can find it easily and vote for it.
Hope that helps!
Beginning on April 4th, we will be implementing push limits. This means that your push cannot be completed if it is over 3.5 GB. If you do attempt to complete a push that is over 3.5 GB, it will fail...
