I would suggest changing the way the user inputs the maximum number of backups kept to be either:
- A text box with detected validation the allows digits less than specific threshold, e.g. < 50.
- OR, a select input, as it is now, but with different incremental seeding, e.g:
- 1,2,3,4,5 ... specific threshold.
- 1,5,10,15,20,25,30, ... specific threshold.
On the other hand, if there is anyway to change these values without hacking the core code, it would be more than enough to me.
