Thank you for resolving the problem in the big preview window where it would jump and jitter AND for adding the ability to change color in the text edit window.
I am old, wear glasses and I have a tremor in my mouse hand and find it very difficult to control moving the cursor by hand and especially from my touch screen. The right cursor bar and the bottom cursor bar are just too narrow. Is there any way that you can widen both bars and both scroll points?
