pfr but how on earth do you know where each window's boarders are when you can't see them?
I don't know where each window's borders are 🤣 - but with my workflow, you don't need to know where they are.
You can think of it as interacting directly on the text rather than interacting with a window containing text.
90% of the time, I just have one floating terminal centered on my screen. Having no border and using the same background colour on my terminal as my desktop background colour brings a very nice distraction free writing environment imo. In some rare cases where I need 3+ windows I'll usually just switch to fullscreen and use tmux for tiling.
