From a random Pycharm doc
Windows in their setup appear like so
Mine look like this:
I miss my minimize button.
How do I get a windowing theme that most resembles Windows?
I want minimize, seeing the path I am currently in, ability to navigate back (with mouse or backspace), creating shortcuts [THAT WORK from the file's directory], and so on.
I am currently using nautilus and gnome (default in 20.04)
The buttons you are looking for (minimize,maximize) are options in 'Gnome Tweaks'. you can download gnome tweaks through synaptic package manager, I think software center as well. After its installed you will find it in the utilities grouping box in your applications menu. labeled as tweaks.
Win look a like themes most likely at gnomelooks.org. headings to look through - gtk themes gtk3 gtk2 and path if your asking what I think your asking, control+L, turns address buttons into address bar.
This is an excellent resource for learning to tweak Ubuntu.
Another thing to note is, I think your on the pure gnome desktop, - on your login screen there should be a branding circle, bottom right corner, - if I'm right click the logo and click Ubuntu desktop, it has minimize button.
