I’m so glad you asked.
If I were to compile a wish list of updates/changes . . .
#1 would be limiting the sidebar index to the selection from the prefix menu. This would eliminate any need to define a restriction to the numbers shown in the widget settings. It would be cleaner, faster and more logical and give the user a feel for how the encyclopedia works.
#2 would be the ability to have the prefix bar added to a page OR the ability to set/have a archive “starter” page that presupposes the prefix selection is “A”. Look at the website. I don’t really need/want an “about” page but I have to have one for the site not to produce a “page not found” error when it loads for the first time. This is a flexibility issue. How are other sites transitioning from blog (which this site doesn’t have/use) to encyclopedia?
#3 would be to never present in the archive page anything but the individual selected term or terms with the ability to limit the amount of text shown for each if multiple items are displayed. The encyclopedia search would display the searched for term(s) in the sidebar index, not in the archive page. If a single term is returned from the search, it would display the term in the archive. The prefix bar would be shown throughout, regardless of whether there was a term to display.
I’m trying to suggest logical things that would speed up the use and widen the scope of the abilities of the plugin. I hope I’m being helpful and not bashing you over what I need and am not getting.
