how to open and work with project folders under my ~/dev folder

[fredflint]

I have a bunch of different project folders all under my home folder ~/dev and I currently open them in a terminal for each folder. So I have a bunch of terminals and then I often clone that terminal and have multiple terminals open on the same folder. Is there a way that I can create a new session and tell it which folder to open? so terminal1 is ~/dev/project1, terminal2 is ~/dev/project2 . they are not related to each other, each is its own git repo (only local for now, not in github) , or maybe i am doing it wrong and should be using tmux instead. it gets hard to know what each terminal is doing, whether I should keep it or close it (but then lose context...)
