You can make borders as thick as you like. The "1px border" disease is a theme design problem.

It wouldn't matter if bottom-right resize handles were standard, but as it is only a few windows have them.

Try holding down <Alt> and middle clicking anywhere near the window corner, I find that far faster than trying to grab any kind of corner or side, and I get frustrated when I have to use an OS (eg. Windows) that doesn't support this.

I know that frustration. I catch myself trying to do that in Windows all the time.
