During evaluating the great new version of the bot tracker plugin for Piwik 2.0 (still beta and in development but everybody can help!! see #2391),
I got the following idea:

it would be very great to have the additional possibility within the visitor generator plugin to
generate in an easy way a single deeply customized visitor - with all the different properties Piwik can track and report

from which IP
which country
which browser
which plugins
which screen resolution

with reached goals

with ecommerce
with abandoned card
...

different bot types
...

The customization of this visitor may be done via dropdown selections

having this possibility
one could easily

• reproduce a problem within another/newer piwik/plugin version
• check during development and testing if a new feature work as it should
• set up one or even several different groups of customized visitors for being used in regular or even automatic testing

what do you think?
