This is not a bug, but a feature request.
DUDU software is great. A lot of things are configurable, and that's where things sometimes get a bit frustrating.
Sometimes it's hard to find where exactly particular option lives. One eventually gets used to finding the right knobs in the right places, but for a new user it's a bit of a pain. Even for a no so new user, it often takes a while to find the right place in the pages and pages of config screens.
It would be great to have some sort of way to search for particular setting, similar to how one can search for them on a regular android phone. You type a word, and get the list of all setting locations with that word. Bonus points if clicking on an item brings you to that settings page and highlights the item.
