After some time you can get used to the new style
I was using it on the test server since a month, after some time I preferred the new one, finding the old one so outdated, I was just waiting to put the new one on the real server.
I am testing options to allow to chose text zoom % on admin page (currently it is set at 90%, since at 100% people found it too big), and I'll try to also add an option to reduce the space between fields (kind of "compact mode").
Here is a copy/paste of info I sent to another admin who complained about the scroll:
On my screen (1080p with small font in Windows & Firefox) I have the whole vehicle page on the screen without scroll. In Edge it is even smaller.
If you use Chrome it is possible that it uses a larger font by default (maybe something that can be changed in the settings?)
For saving or jumping to a field, there were (and still are) some shortcuts.
In general to submit a form (add/update/save/post) there is Alt+Shift+S (or Alt+S depending on your browser settings).
Each field of the vehicle edit page has a shortcut, the one I use the most is Alt+(Shift+)T for the timecode field.
There is also Alt+(Shift+)A to add a vehicle and Alt+(Shift+)U to upload the picture, both from vehicle page or after adding/updating a vehicle.
I was not sure what size to allow for the fullpic link, as Mike tends to overuse it. He is the reason why I changed the limit
But note that you can yourself replace "pic" by "fullpic" when pasting the code in the comment
I agree that on the picture upload the copy button that gets active with tab is a little annoying, I sometimes accidentally activate it when I want to upload a second picture
The copy button is probably useful for many users (not only mobile), I'll check if it is possible to avoid focus on it. In the meantime, you can also use the Alt+(Shift+)U shortcut that I added on the "Upload another picture" link like there was one for the other "Upload picture" links.
I am afraid of what will happen when the front-end will change
As we will have to make the site more mobile-friendly some day.
One solution would be to have two separate versions, one with the old layout and one responsive for mobile, but it is a lot of work.
Anyway there are so many other things to do, it will not arrive quickly.
