This is a minor annoyance, but I keep doing it, so maybe there's an easy fix. If you enter a value into one of the text boxes, and immediately press the Subdivide Edges button, it doesn't use the value you've just entered. It seems that the button press even is firing before the new value has been committed to the text input. For example, select and edge, then open this window. Click into the textbox that's currently holding the number "2". Type "10", then without pressing anything else or losing focus on that text box, click on "Subdivide Edges". It will create two subdivisions instead of 10. I'll probably eventually get used to this, but if it's an easy fix that would be nice.
