Add Keyboard Input for Sliders

[zixuzhuang]

I want to start by saying that this plugin is really impressive and useful. Great job on it!

I've found that adjusting parameters of custom ComfyUI workflow in Krita through the sliders can be a bit inconvenient at times. It would be much more efficient if there was an option to manually enter values for the sliders instead of only dragging them.

Would it be possible to add keyboard input functionality for the sliders? This would make the plugin even more user-friendly.

Thanks for your work on this!
