GUI Filter: Display only functions / methods with profiled lines

[mucmch]

Thank you for this great project!

Is your feature request related to a problem? Please describe.

Currently, the GUI output has the boolean option "only display profiled lines".

If true: It only shows very few code lines and no information on the context, making it hard to grasp what this part of the code is doing and in which context the line of code gets called. If there are line breaks, it might even show incomplete statements.

If false: Depending on the code, might show a full file with thousands of lines of code. Of this code, only a small fraction might have run at all. Most of the code might be completely irrelevant for the task at hand.

Describe the solution you'd like
Adding a third option showing only functions / methods that contain profiled lines.

A potential alternative could be, have an option to show the profile lines within their context, e.g. by showing the previous and next 10 or so lines of code.
