Probably a stupid question but I like the spoon interface and want to make some changes.
Lets say on the design interface after you load spoon, I want to get rid of the Steps that I do not need on the left palette to make the program more lightweight.

If I want to remove 'OLAP Input' or 'XBase input' or whatnot from input,output or other folder looking icons, where can I look for to modify (on the source code )so that they dont get loaded. I am totally newbie but my goal is just to make it work with MYSQL and oracle and also limit to use fewer step materials.

I want to understand the architecture of how spoon gets loaded to make it more customizable.

Help please..
