I did a poor job of explaining the overlay stuff. Here's a sample screenshot: https://files.catbox.moe/dk8gt3.png
In this case my browser is occupying around 4/5 of my screen horizontally and I'm using the column layout. You'll notice the text on the post title on the left doesn't adjust. It's not always though, as sometimes other posts with long titles look fine and adjust accordingly. Not really a big issue, I just wanted you to know in case the aesthetic bothers you.
Thanks for the responses for the other stuff. I understand some are limitations with lemmy itself. And good point on the search, at least I know what to do now if I need to narrow down queries.
Top from the past 6 or 12 hours works better than Hot IMO. It feels more like the traditional reddit front page.
