hehe, here I go
@ installers -- hmmm, what happens when I have install-"ed" something? Does the name change? A bit confusing for me. I like the term "module" better.
Installer for me is a utility that allows you place items in a location ready to be used. ie, those programs that litter your system with funky files that make you feel skeptical about.
@ content Fields -- like this! Much more off and going over TV -- also for a newbie the term will peak more interest in regards to looking up the term versus TV which might cause brain farts or soemthing. However, the term "field" through me for a quicky since I was thinking in HTML terms but after a reread I realized that I was right. Strange that a good use of terms made me double think this one. However, after the realization CFs are way more easier to visualize and understand.
@ capsule -- what??? I totally imagined either a "space" capsule or a "Tylenol" one. The term snippet comes across for me as a short/brief script. hmmm
@ widgets -- Like Ryan mentioned will now most likely be confused. I learned back in university that "widget" was something that a company produces -- lolo, probably easier to say and write than "thing-a-mu-bob", "doo dad", "wha-cha-ma-call-it’s".
how about -- affects? however, PhotoShop uses the word "effect" ewww, my understanding of the two would make affect a better choice but ... errr ... "effects" might be better though.
@ plugins >> extensions
@ modules >> plugins
the reason is that if I keep rereading the definitions the difference gets a bit clearer each time for me.
I’m thinking that the core is very simple thereby any change to the core or way things are done the simplicity is now in a more advanced stage -- basically extended. thereby negating the "plugin" idea -- almost got tangled in the "what’s a plugin or module mentality".
and calling "modules" a plugin because they are things that you plugin and work. They don’t really extend the system but add a new functionality (err, yeah, yeah, but isn’t that "extending

?" -- hehe yeah but let’s not go that route

) I’m totally thinking about PhotoShop at the moment.
@ content vs document
hmm, I’ve always thought that content was what was in a document (page). The term document seems more like a file to me -- something like you’d download from the net. While content brings up images of "news" and "information".
In the tree menu the term document seems very appropriate while if I were actually editing I wonder if content might not be easier to understand. Of course, you’re editing the document but the literal focus of attention is on the content (non-physical) rather than the paper (physical) side.
ok, that’s my 2 bytes for the moment.
