Versions from 3.3.6 to 3.3.8 introduced a bug that I could not live with, namely the estimate function in Proteus manual mode did not work. This version seems to have fixed it, thank you.

I also tried the 3 functions for presets, create, delete and update and they work well. I did run into a little inconvenience: I want to create a preset for upscaling to 4k at a fixed 8k bit rate so I select the built-in “Upscale to 4K” then I changed the encoder bit rate from “Auto” to “8k”. Now to create a custom preset, I have to change the preset to “None” first before I can create a new one. I wish that create function (+ icon) is added to all the built-in presets in the future.
