When you create a new tiddler and a tiddler called 'New Tiddler' already exists...

[simon]

...it opens the existing tiddler called New Tiddler for edit. This is confusing. Perhaps it should use 'New Tiddler (1)' if 'New Tiddler' already exists. And 'New Tiddler (2)' if that exists and so on. Same for New Journal or actually any new tiddler button, eg this <<newTiddler title:AnyTitle>> should behave the same way it AnyTitle? already exists.

maybe the String.prototype in that position is a bad idea? Could refactor it to a regular function.
