I used Joey for years for Reddit and it has an incredibly useful navigation feature that would allow you to use arrows to jump through every top level comment.
Thunder would benefit so much from this feature.
Trying to upload an image but it says “Error occurred while uploading”.
Hey there! Comment navigation should be available on the latest general releases on Google Play and App Store (it was introduced in a previous version v0.2.2+15). It could be possible that you had that option disabled (Settings -> General -> Comments -> "Enable Comment Navigation Buttons")
The releases on GitHub contain the latest nightly builds of Thunder, which are updated more frequently but are more prone to bugs since they are more "experimental" in nature. I hope this clarifies some of the questions!
Thanks so much for all of your work!
