I have a simple and i think very useful suggestion. When searching for a keyword or text in the Arduino sketch, it would be really helpful if the scroll bar on the right-side of the screen would show highlights about where these search keywords have found a match.
For example, in Google Chrome browser, this functionality is already implemented and it is extremely useful. I wonder how hard it could be to implement this, but hopefully, it should not take too much work/time.
Here is a screenshot to illustrate what i mean.
