I think Home button appeared in early days of Tiddlywiki 5. It can be used on the sidebar (page controls). On click, it shows the default tiddlers in the stroy river and refreshes the url to correct location.
But it is a button! Why we cannot assign some actions to it?
What do you think to have a slot under $:/ControlPanel > Basic > Default actions
like Default tiddlers?
For example when I click the Home buttons I like to create a Journal tiddler for today if one does not exist.
What do you think? What other actions do you like to have?
Note: I do not want to create another user defined button! I like to see how better I can use the existing Home button!
