Finally done with the plugin, added all the bells and whistles.
To install, you just put the "SOB.rb" file in the zip file under Plugins folder. This gives you a nice menu addon as seen in the following picture:
When you click on that menu option, you get a basic dialog box:
You enter some parameters and voila! You have a nice dox design. There are 3 choices for side panes: None, interclocking and stacked. You can see why I named them as such when you create the different designs: Interlocking has interlocking side panes, they are sturdy but sometimes hard to assemble. In stacking you first put the short sides' panels, then long sides' panels stack on top of that because of the tab adjustment.
Just tell me what you guys think. Can change dialog box stuff easily. Also I can upload it to SVN if you want it.
Enjoy!
