Twitch sub button on other parts of the Twitch app.
The new experimental sub button is only on the expanded info page for a mod. While I can't speak for every user, I feel like most users download their mods from the search list rather than the expanded info page. The reasoning for this is that it is quicker to download mods you are already familiar with that way, and there is no clear indication that an expanded info page exists from the search page.
In my experience with the twitch app I only view the expanded info page if it is for a mod I am not familiar with. However when it comes to supporting mod authors, I would rather support the authors who's mods I use regularly, rather than some random mod I am seeing for the first time.
