All you need to do is setup a second "business" account on your personal account which lets you have a second completely separate Google Photos library. The interface is fast, easy use and to find stuff and you can upload as many screenshots as you like fore free, forever.
Basically I screenshot everything I like and throw it into Google Photos. You can create albums to categorise, if you're into that, but I find it a waste of time as it's impossible to upkeep. I usually only reference the last month or two worth of saved stuff and move on anyways.
Google Photos is the best.
