I have downloaded and installed the custom firmware 2.0.3 for the Q10 Pro Android 7. It looks good and a great UI improvement is that the names of the folders is smaller than the official firmware.
I don't know if this is the right section to post suggestions/improvements but I will try anyway

- I have a folder that has over 1.300 folders in it. When I access this folder, either the application stops or it will give an overview of all the folders and takes about 14 - 17 seconds to load. On the official firmware both actions take less than 1 second to perform.
- When browsing these folders I usally use the skip and go back buttons to go faster from A to Z. This does not work / or is not enabled within the custom firmware.
- It would be a nice to have to set an option where the font of the folders can be set to a smaller font. In a single overview I can see 9 folders. Would be nice if you can select a font range that can display 5 till 20 folders.
