My issue is as shown in the screenshots. I have a Surface Pro 4(?) attached to an external monitor (1080p) and the right side menus are just never correctly displayed. Maybe this is a feature request, but why is this the only application that doesn't let me resize the side-panel.

On 1080p screen default view

On native 2736x1824 Surface screen

It's incredibly frustrating that none of these panels can be resized, but as can be seen in the "Enable fan if..." dialogue, in this instance I am unable to even see what value is in there. Particularly frustrating as this is an incredibly potent feature that has a big impact on a lot of smaller prints.

In the main screen the new beginner / advanced / expert toggles are mostly hidden, I'm unable to access or even see any of the new UI in regards to per-object properties, and all throughout the UI there are baffling UIX designs that I can't get around because absolutely nothing is resizeable in Slic3r.

It goes without saying I think you guys are absolute champions, but these mind-blowingly simple issues are completely ruining the experience for me, and I know are a big point for all of my friends and why they stick to much more basic slicing packages. You're doing an amazing job surfacing all of the incredible features and work the community has poured into Slic3r, and I hope you can find some way to let users like me and my friends make the most of your hardwork.

All that amazing effort and I can't get to appreciate it! :(

HiDPI should be implemented in the upcoming Slic3r 1.42.0-alpha7. Closing.
