if we are talking real estate on the page, there is a whole pulldown menu for configuration. install a few add-ons, and that menu gets quite long.
is the config stored under maximum values, product listing, or stock?
example, search for product in the developers tool config search; on one of my dev systems, that comes up in over 20 different groups. what a pain to find the one that one is looking for!
and with regards to why specific configs are stored in which groups, well you got me. min values, max values? those are actually groups? everyone has a different opinion about which group a config should be in... and what groups there should be.
searching for a config is the easiest way to go, in my mind.
and with regards to the rest of the items on the developers tool kit, grep is a wonderful tool. i use it frequently.... i would say daily... maybe hourly.... but always on the command line and never from the toolkit.
best.
