UI: pprof integration: View - > Source missing ctrl+F (search) support

[Owyn]

Is your feature request related to a problem? Please describe.
I'm always frustrated when I open View -> Source and I try to find anything there, e.g. my functions - because there is no search there, I press ctrl+F and it doesn't do anything

Describe the solution you'd like
Ctrl+F simply search support

(or/and) better a function list at the right with grouped (by package) functions I could click to go to them on this page

Describe alternatives you've considered
Now I have to select+all (ctrl+A still works here, thank god) then copy it into my Notepad and do the ctrl+f thing there
