Yeah, I was totally in the "one tool for everything" camp for so long. What finally flipped it for you? For me, it was trying a different program just for the pen tool because mine kept glitching. Now I jump between two or three without even thinking about it.
lmao the "one tool for everything" camp was my whole personality until my main program crashed during a deadline. Turns out stubbornness isn't a good workflow. Now I'm like you, just hopping around without even realizing it.
