After updating to Ratio 5 I noticed that some of the features which made me switch to Ratio as my primary launcher are now gone.
-Double tap to lock (removed)
-Hiding apps (removed)
-Changing app icons doesn’t work for me (bug)
-App drawer shows all of your apps (there is no hide option as mentioned above)
If these features matter a lot to you then do not update to the latest Ratio version just yet until it gets sorted out by the developers.
