Vertical tabs for page edit screen

[Ivan Gretsky]

Good day everyone!

Last year we had some great improvements for admin theme customization. Big thanx to @bernhard and @ryan. But there is an area of customization that is not so easy to approach - changing the layout generated by process modules. For example, I want to change how tabs on page edit screen are positioned. On one project of mine I got so many tabs, it is reasonable and preferable to have them on the side to the left, not on the top of the page. Preferably sticky (see the screenshot below). Did anyone try to implement something like this? Did you succeed? Could you please share how you managed to do it?

I am pretty sure I cannot do it just with this module. I have seen something similar done in Admin Theme Boss with jQuery UI Layout Plug-in, but I'd rather do it in php))

Please share your knowledge!

PHP? Really? All you basically need is some admin CSS. 

#PageEditTabs {
    position: fixed;
    top: 261px;
    left: 0;
    flex-direction: column;
}

^ this surely doesn't look fancy, but it could serve as a starting point...
