The first version of Boost for Lemmy is almost ready. If you want to test the app for bugs and give feedback before the app is published, follow this link https://play.google.com/apps/testing/com.rubenmayayo.lemmy to enable an early access option on the Boost for Lemmy Play Store listing.
I can't seem to expand images or download them in comments. Other than that, it's just been great to have Boost back!
