Thank you for the detailed feedback - really appreciate it.
On Episode Sorting - although the default sort is "Latest episodes" - it's actually sorted by date added - so if you manually add an episode the is older it will go to the top. We're going to work on adding more sort options.
On premium signup not working - what device / os are you using?
On show page tile option - just to confirm do you mean viewing your list of shows as a grid of images without text?
On queue as main tab - we are exploring this - hopefully can share more soon.
On pod link as default link shares - if podlink expose the podcast guids somehow which I think they might - then we could do this and still have the shares display in our feeds.
Let me know if you think of anything else.
