Twixtor plugin alike

What tha hail?? No shooting options? Just shoot 240 on 720p? What about 1080p in 120? Or trying to slow in 4K 30fps? 4$ guys??? Bad bad bad for app that could be awesome....For 4$ would like to see more options like changing picture gamma, saturation, tiny, sharpness to match oTher cameras in post, would like to see manual camera controls shutter speed, focus luck...
Needs more work to worth the 4$
