First off, I must say this is a great portal! I previously had gencportal installed but had too many errors. This one is a great start and has potential as well. Very well done.
For further development, it would be nice to choose which boxes go on which side (LEFT or RIGHT).
Also, exclusion of certain boards from the "Top Boards" List would be nice. (As I have Several Archives Forums where I move old topics... And I do not want any Archive Boards showing up in The Top Boards section). So perhaps a block that says:
[Board ID's that you do not want counted in Top Boards]: [ 2,5,15,23 ] (Separate by comma)
Lastly, Custom Boxes would be nice to add as well (Such as SMF Shop Recently Purchased Items, SMF Pets Leadersboard, SMF Arcade Latest High Scores, SMF Downloads Latest Download Additions, etc).. The possibilities are endless..
