An option to move the app to external storage?
Title. I would like to be able to move the app to the SD card as my device constantly suffers from lack of free space in internal storage (yes, even ~100 MB of space freed does make a big difference for me).
Might be able to move the cache around, but the app location is probably outside of the purview of the app itself.
That is still better than nothing :)
I'm not sure how exactly it works in Android, but I can see internal storage being freed after I move freshly installed, never launched (so, cache size should be zero) apps to SD, so I assume it does something with apps themselves as well.

I think I get what you mean now - to make an app movable, the developer has to set a value in AndroidManifest.xml, then the OS itself will offer an option to move that app elsewhere in app settings.
