Hi direx, thanks for the very useful app. One suggestion I'd like to make is having a configurable upper limit in "Setting" to limit the range that the slider controls. For example, I could set max limiter to 850MHz and the max frequency the slider can go will be limited to 850.

I'd like to see this feature because I did accidentally drag the slider too far a couple of times while adjusting frequency. The limiter would serve as a safety feature in such case.
