Add folders in Schedulers

[printCode476]

Hello thanks for this awesome project, it help me everyday.

I want to add a new feature to the schedulers : folders.
Similar to the folders in timers, it will be nice to have folders in schedulers.
Basically have the same functionality of the folder in timer like trash and default folder and one more : the possibility to turn on and off a folder so that it turn on and off every timer on this folder.
Use case:
A working, and holiday folder to switch easily between holiday mode and working mode.

I think I could help to implement this feature to me it's not that hard, we need to modify the scheduler entity, DAO and config file, of course in timer-scheduler, we could reuse some code of the folder of timer for the folder of scheduler and after modify the code for integrating this feature for backup.

Is it a good idea ?

Thanks for creating this project.
