Right.

It was a very good tool before they did that. I still have it installed 
in some old phone or tablet. I don't understand why they did not revert 
what they did bad to continue business.

But there must be some other similar tools that do that cleanup. I have 
another one, but it is part of a brand customization.

Right.

Actually, recent Android versions do an automatic cleanup of apps that 
have not been used for a number of months. I have to go round ALL apps 
to disable this feature. It is a nuisance having to configure them again 
when I do need them. And some of them are tools that do things I need in 
the background, not having to open them for months.

Right.
