Just two cents :
1) would be nice to have the text baseline (for control name and numbers) aligned on the middle distance between top and bottom inner borders
(on my Mint Maya text top touch the colored area of the slider top border )
2) Probably the numeric input control can be activated just on the right mouse click over numbers (and deactivated by an outside click or when the focus is lost ) - this way an overlap of events can be avoided
..not the third coin here - but a suggestion - it would be perfect to have a visual indicator (..like a color change) when the cursor make the switch from vertical arrow (normal mode) to horizontal arrows (precision mode) and the mouse cursor is still over the slider.
as is now, is not very convenient and I observed I have to put a lot of focus and attention on the slider area ..but with the old slider control everything was just point and drag
..probably for the peace of mind and commodity a combination of Ctrl + Drag on the slider will be a better choice for switching to "precision mode" - a status bar notification can indicate this action when the cursor is over the slider or when the slider is activated in "normal" mode.
