When at Kazuki's under his "Services" menu, when splitting a stack to transfer over to his crafting menu, the mouse cursor doesn't move with the slider properly. If I select the slider and VERY slowly move my mouse left or right, they stay more or less synced up. If, however, I move my mouse to the left or right at a reasonable speed, the mouse moves far faster than the slider, causing a desync.

For example, if the slider is all the way to the left, and I quickly try to slide it all the way to the right, the slider might move 25% of the way to the right, while my mouse is on the far right side of the screen. If I then move my mouse back to the left, without ever having let go, it registers as being to the right of the slider, thus increasing it, despite my mouse movement being directed to the left, which feels like it should decrease it.

Also sliders in general don't keep up with the mouse movement currently, should either match the speed, or the movement, but not the relative position of the mouse. ver 0.8.11.600

An numeric input option would be great too. Splitting stacks of twigs for a mere few twigs (for example) when the full stack is over a thousand is somewhat tedious

You can click the number on the left to input a number, but visually there's no way to know this(will be improved in the future).
