While it still is out of the official app, I'm currently working on an android app for mod-tools (disclaimer: not affiliated with the developers of the toolbox addon). It's in a sort of beta right now (as in not yet promoted, but already released, undergoing polishing), but it's coming along nicely and already has removal reasons and usernotes. You can follow along with progress in /r/mobilemod.
By, "the new app", do you mean the official app? There are many, many third party alternatives that are better.
Specifically for modding, this came out recently.
