I'd love to suggest a 'random text' widget that can be used to display random bits of text e.g. quotes. The config could be three fields:
Self-explanatory e.g. "Random Quote"
2) Separator character
If none is specified, then the newline character is the separator. Otherwise, it could be specified to be anything e.g. "###" Perhaps, max. 3 chars.
Rationale for this is that one might want a random text item to contain newlines etc.
3) Random text
Just one large
<textarea> field to type the random stuff to be displayed.
OK, I admit, I'm too lazy to do the coding for this; it's been a long time since I did anything that's programming.
Perhaps someone already has done something like this that stores into a text file? Then you could convert that to a WordPress widget :)
This'll be a great addition for people who love to have random quotes or taglines on their sidebars!
