I found two issues on your recent release of JKI Flat UI controls V2.0. Those details are follows,
1. When I changing to true state on settings control, it shows different image instead of settings image.
2. When I try to enter values on numeric controls, the cursor hover expending beyond that control size. Typically, the cursor hover size would be within the numeric control size.
I hope, these information's may help to improve changes on your Flat UI controls V2.0
