Here is a hopefully minor thing…
Reddit has multireddits where you can have a few that follows a certain selection of subreddits under a label. You can have multiple ones defined as well. Therefore, you can have a view for all things news (following multiple news things) without having to view those things on your main home feed (as well as any other defined topics that you can think of).
It would be nifty if such a thing could exist inside of Lemmy as well.
There is a website of a person who catalogs Texas Instruments calculators. You can wonder over to the graphing calculator section to see how many different graphing calculators they made along with a bit of information on each one.
