Edit: Just pushed v7.91.0 which should fix the search issue for you. Reddit recently made some changes which made things a bit unstable.

Thank you for taking the time to write a review. Reddit has been making a ton of changes including deprecating core parts of their UI so it's been a touch challenge to simply keep up.

I will take a look at the search bar issue and get it sorted out in the next update. If you could let me know which version of the reddit UI you're on, that'll be super helpful.
