I’d like an app that can let me choose icons for each of my apps, from any of the packs that I have installed. Once I choose for all my apps, I want to create a standalone app from the set I created.

I have the app Iconeration, which does almost all of this, but the apk it produces only indexes what icons to use from what existing packs, it does not actually embed them within. Now, I could save the icons I like and create a pack from scratch, but I would prefer if that was all automated.

And I’d like it to be FOSS preferably.

If there is such a thing, please let me know? Thanks.
