I used WP 1.2 for a long time, and had a template switcher with 5 or 6 of some great pre-made templates that were available. The content, and the sidebar content were independent of the templates, and it made sense that you could choose a different template, yielding a completely new look and same content, but required no editing.
In WP 1.5, themes have come into play. While I'm very adept at php/html, I've had to learn CSS and have a pretty good grasp of what's going on (with some help from some fine folks here, thanks!).
My question/issue is this: I've created a theme called "mine", which is essentially a copy of root's Trident. I've edited the sidebar menus to reflect the content they should, etc, but those edits are in the \themes\mine directory. Am I missing something, or in order to implement a "theme switcher", wouldn't I have to go into each and every theme I wanted to make available and edit the content to reflect what I want in the sidebar, etc? I'm certainly not complaining, however, it didn't used to be this way, and while I'm learning LOADS about CSS and having a blast, I'm a bit confused as to how WP 1.5 themes make it easier, or allows "theme switching" without some serious editing of each theme you'd want to allow? Maybe they don't, or maybe I'm just missing a rudimentary piece of why we're using themes now, but I'm confused nonetheless.
I don't want to waste anyone's time, and I've read the differences, etc, but if someone could explain I'd sure appreciate it. I feel like I'm missing something here.
