I am currently at war with google docs and notion re: memory usage. gmail takes something like half a gigabyte of memory. I had a notion database where each time it loaded an additional 25 rows, memory use went up 400MB. It only got up to 200-300 rows total before it died. I gave up Sublime because of memory usage, but the alternatives aren't much better. I'm getting ready to trade in my 8gb Mac for 24gb to help with…
Consider BBEdit. I’ve been using it a lot more these days, now that its competition has skyrocketed in CPU / memory.
I'd love to buy it, but while I'd be happy to pay 99 bucks for a perpetual version with upgrades, I'm not willing to pay 50 dollars every unknown amount of time. Even if I might pay that for a known 5 years worth of updates.
