Service Capture is painful to use to watch a specific request. Tamper Data for firefox does a great job at allowing you to filter requests to only see what you want to see. E.g. suppose I only want to watch requests to www.abc.com/servlet.jsp . I should be able to type 'sevlet' or a regular expression into a 'filter' textfield and the results get filtered to show anything that matches the search criteria.

to add to this, have the option to maintain an ignore list

You can maintain an ingnore list in the Tools->capture dialog Its just a list of regexp that are "excluded" from capture.

I think that "wish" too must be in the "filters" post:

please add if it possible a colorizing of a rows rulled bu regexp or something else
for example if i'll trace something like
- the background of that i'd like to make a red, and is yellow e.t.c.

or for example i'd set up that all of mysite.com/....... will be whitecolored, but mysite.com/images/...... will bee with blue background
