So i found this library and i thought "No way, this is really useful!", in this library you can store any value in the browser, the data will never be deleted unless you use the block:
clear data in browser
I think that this is really useful and should be an official tab, but this is just my opinion
Do you mean making it a regular category that's shown to every user every time you open snap? I personally don't think that's a good idea, since this isn't something everyone is going to be using, and it fits more as a library.
The correct block you should be using is remove key: [] in browser. Please do not use this block as it will clear all data stored using the Database library no matter where it originates from!
