Enhancement purpose

We already have BGR for keys, it might make sense to implement BLR as well 🤔

Solution

We should consider extracting common bits from BGR into generic implementation, then re-implement BGR as well as BLR on top of it. We should probably also consider adding commands for both.

Why currently available solutions are not sufficient?

This would allow people to schedule licenses for activation, and also make it easier for plugins dealing with license keys (e.g. @Citrinate plugin https://github.com/Citrinate/FreePackages)

Can you help us with this enhancement idea?

Yes, I can code the solution myself and send a pull request

Additional info

I'm not yet sure what to think of it, so this is currently under evaluation, but I'm positive for now.
