I'm currently working on, yet, another restructure of SL add-ons. Specifically two things right now,
SLCore which is going to be a core configuration & module control add-on, and
SLModule-1.0, which is an associated SL-specific library for building Plug-In modules.
SLCore eventually will use it's own GUI configuration menu instead of a Waterfall menu. Together with the
SLModule-1.0 library, modules (such as Clock, FPS, Bags, Exp, etc) will be independent add-ons that will function as modules controlled by SLCore. This will allow users to selectively choose which modules to use and not to use without the bloat of unneeded modules.
This will also expand the SL interface for other add-on authors to build SL Plug-In modules of their own design. The core idea of this will be the same as always...lightweight text-based stat tracking, and the library and structure will cater to this specifically. However in the future, this may expand into other add-ons of which I've been interested in building but just haven't begun yet (ie. Action Bars, Minimap, Art/Texture Injection, etc).
Currently I'm at what I would estimate as 15% completion for this project. Any insight, opinions, suggestions, ideas, etc. are more than welcome.
