Suggest adding a vertical ruler when clicking some pipe stage

[shuheque]

Hello,

This is really awesome tool, but I found a bit incovenient when I try to check how many cycles b/w one instrctuction and some distant instructions else, e.g. in below figure, the first and next retired.

Consider to add some vertical cursor(s) when clicking on a pipe stage? even 2 or more and a diff can automatically show on statusbar, somewhat like waveform tools such as synopsys VERDI. :-)

Hello,

I have also thought it would be nice to have vertical/horizontal rulers.
I think that this would be relatively easy to add, and I will add this feature.
