Instead of constantly clicking +5's to add a resource to an object/population, we should have a text box to pop up where we can type exactly how much we want of a resource.

Instead of sitting with an auto clicker running to add 10,000 energy credits to a star, we just select energy credits, a box pops up where we can type 10000, and it'll add it in very little to no time at all.

This should also be a thing for all options that have the ability to add/remove resources/features, so we don't have to constantly click, or go afk with an auto clicker until we get what we want.

The game already has a system where you can rename ships, leaders, fleets, stars and whatnot, so something like this can be used to add resources in the same way. A lot less time consuming, needless to say.
