Pro tip : put your .config folder in a partition on an SSD to load your applications faster

I did this a few years ago after noticing that while, for example, Chromium did load fast, the icons in my shortcuts bar loaded way more slowly.

After doing this, everything went fast.

Pro tip 2 : If you're a gamer, some games shamelessly store saves in that folder. Have 5-10Gb to be able to run for years without running out of capacity (went out of capacity yesterday with ~3.5Gb after 4 years, cleared only one. I might have to move or expand that partition)
