Woah, thanks for all your feedback, I'll definitely try to get all your issues fixed!
I tried changing my all region settings to Norway but shortcuts still worked for me. The hotkeys tab in the settings window will eventually let you customise all your hotkeys so I will work on that and see if that helps identify what the problem is for you. I didn't know about Alt+S and Alt+A in Hammer, currently Sledge is hooked up with the [ and ] hotkeys for changing the grid size.
At the moment the 'background colour' applies to both 2D and 3D views, but I can create a separate colour for the 3D background if you think it's needed. For the viewport labels and switching between wireframe and so on, that's a planned feature but it's not available yet. I don't know what the default FOV of Hammer is, it could be figured out by trial-and-error but I don't have the time for that
The missing selection dimensions in the status bar is a bug and I will fix it when I can. Same for the bug related to changing the FOV, I can't believe I made a bug out of something so obvious!
I'll work on adding the missing features in the texture browser.
For the camera tool, thanks for your explanation. I've never actually used it so I wasn't aware that it did all that stuff. Is there a tutorial or something that shows all the features of the camera tool in Hammer? That would be very useful for me. As for not being able to move the "pointer"... I tried doing that but the maths was too hard so I gave up for the time being... I'll try and approach it from a different angle so it works as you expect! I intentionally turned off snap to grid because I didn't think it was useful for cameras, but I will turn it back on if that's the expected behaviour
Again thanks for your feedback and please don't hesitate to continue telling me about bugs and missing features! I will try and get most of your bugs fixed in the next week or so as I am on holiday at the moment
