@ramin_hal9001@emacs.ch I use the same C-x b as well. 👍
I just like static access points for some files (such as todo.org, repeat.org, chatgpt, dashboard, etc...) things I refer to many times a day. I set it so that I can flip through the tabs very quickly back and forth so it's generally faster than C-x b and typing a few letters to bring up the relevant buffer. Also, flipping through them, I realise I lose track of things sometimes in my head and a visual reminder when I'm flipping through allows me to remember to do something on that buffer.
