I copied $:/core/ui/Buttons/save, and changed the tags of the new tiddler to $:/tags/EditorToolbar. I also checked this button in EditorToolbar Visibility.
But this button did not actually appear. Why is this? Or is it because some styles are hiding it?
I don’t know if this is the “official” way to do it. I cloned one of the menubar tiddlers and over-rode the caption field with the wiki save button transclusion.
But I am not trying to save tiddlywiki as html file. I am trying to save the currently edited tiddler by putting the save button in the edit field so I don’t have to slide to the top to click the save button.
This should put a tiddler-save button in the editor toolbar. However, it is a different size than the other buttons. The next step would be to track down the classes used for the other buttons and apply them accordingly.
