For a brief moment, the opacity slider for this app’s “1967” filters returned, and then just as quickly, it was removed again. Is there a reason for this? I read the reviews from many users who utilize this app and almost all of them echo the same thing; where is the opacity slider for the “1967” filters? I love this app, but the tried and true filters in the “1967” group are all I want to use. It’s very hard to want to use those (purchased) filters when the filter is stuck on max opacity with no way of adjusting. Devs, could you please bring that back and stop removing it?
