currently I enter a description of a category when i make that category. Blog visitors do not see that description. One or two word category names cannot convey the scope of the statgory. Add a few more words in a tool-tip (hover-over) and the reader knows what to expect. We have hover-overs on other sidebar links (e.g. Blog Roll) let exten d that for consistency.
Experience: Novice - no coding no plugins (that I've been able to make wor, no 'hacking'.
