Be able to install other applications from specific repositories

[marjuanm]

Hello, how are you, I have installed your application and it is quite good at keeping the installed software updated, however I don't know where you download the applications from or how you compare if there are more recent versions.

I suppose that you have an "official list" to install applications, but it would be good for that source to appear in the configuration and be able to add others so that, if any application that we have installed and is not found on your list and exists in another repository, it can be update.

It would be something similar to how applications like synaptic and other Linux applications are configured; these allow you to add, edit or remove repositories.
