Gimp has always been such a lifesaver for me. I’m glad to see it still has been getting improvements!

1. How much are you spending on your cards every month???
2. Why not have more than one card for different things, rather than cancelling cards?
3. You generally want to very rarely cancel a credit card, I recommend finding one with no annual fees and sticking with it. You can always have more cards after all.
4. A spending limit doesn’t really mean anything if you payoff your credit early, you can always request that your CC company release your credit early once you pay it off early.
