More RAM. I've got 20GB now (4+16) and it's just never an issue anymore no matter how much I've got open. Sure, I can fill it up if I tried but... if I'm not purposefully trying, it doesn't happen. Previously on 8GB I'd have to quit a few applications to run a big Factorio map, or my browser might run out if I didn't restart for browser updates in a few weeks.
It's one of the few nonessentials I've spent more than a few tenners on (I actually initially bought 2x16, but asshole lenovo decided it was a good idea to fixate one of the two slots to 4GB...). It was fairly cheap, not sure if that's still the case or if you need to wait another six years until prices reach 2020 levels again (iirc in 2013 you needed to wait five more years to get the same amount and speed for 2012's prices).
Yeah I was going to go for 16G in 2018 but then didn't find a laptop I actually liked, everything was disappointing (turns out computers just don't get faster anymore, at least not per core, and some of the higher-end stuff didn't have Linux support at all, and not only WiFi drivers or so but actually unbootable or major issues on the latest kernel), so this was kind of an in-betweener while hoping to find something nicer in 3-5 years depending on how well I'd end up liking this one.
