If possible, maybe we should draw the "minimize", "maximise", and "close" icons like a normal windows APP with title.

[dzhou121]

something like this

Normal window:

Maximised window:

Full titlebar:

@dzhou121 few things:

• do we want lapce logo in titlebar? current position is ok? same for colour? which platforms will have logo? for example VSCode has logo on Windows, but not on macOS due to window controls on left side

• do we want title? what should title have? should title be same as "os" title (currently it's workspace/folder name)

• do we want window controls on windows to match perfectly? standard Windows window controls have big padding between each other. they also look a bit blurred(?)
  

Example of draggable lapce:

Lapce logo only for Windows.

Probably yes for Windows only.

Yes please if that's not too much of trouble.

I'll try to match it as closely as possible

The only thing left is to add dynamic title to show workspace name but I haven't figured that out yet. PR can be merged and I'll push fix for title later.
Also, restoring window currently doesn't work from window control, it works on double click on titlebar though.

Thanks!

I'm perfectly happy with it for not showing project name, because it's already at the very left.

The restore thing might be a Druid thing. I can look into that.

Changed titlebar height on Windows to match most other apps and improve readability slightly
