I haven't had too much time to work on this lately, between work and school coming up soon. But I have taken a few minutes to tinker with the interface some, to make it look a little more MT-ish. I'll try to get a little more done on the backend this week. I'll also explain a bit more of what Kristine and I have in mind for the central plugin site.
As always, feel free to comment on the plans so far. I want input from the MT community at large for a project like this. :)
Could you possibly implement a way to access the plugin's documentation easily? When I'm working on a template I hate having to locate, find, &look up what plugin does what I'm trying to accomplish, what tags to use, & how the tags are used. There also should be a standard format &way for the authors of the plugin to enter in info into the *plugin.pl file that can be extracted into the Plugin Manager later. Maybe (for example) there should be a field or option for the author of the plugin to keep a file/image saved on there server notifying us on the current release & if the current version has been updated. Well, that's just some of the things I'd like to see.
