• smaller icons, especially for the forums listing, will make it easier to scroll through things keeping overview.
• change the rules to allow double posting as long as each posting goes into a seperate branch in the thread's tree structure. This will make threads easier to follow, especially with thread mode, as posts belonging together are actually displayed together as a branch and not all linearly which might make it hard to understand contexts
• make a mode similar to hybrid mode that displays all posts at once but still has a tree structure that allows jumping to posts.
• possibly write up some script to generate a giant thread view in which all forums, subforums, threads and posts are displayed as equal nodes.
• do not inline the css, but just put a reference. This not only increases cachability, but then you can also make it possible to change that reference's path in the options so users can make it point to their local css files for great customization.
