After discovering this discussion about enabling the browser’s back button, I realised that this could also be used to link between wikis.
Here’s my problem though: I always have all my wikis open in my browser, so I don’t like that when I click a link to another wiki, it creates a new tab with that wiki open, rather than navigating to the already-open wiki and simply opening the tiddler.
This seems to me more of a browser issue, but is there any way around this? Ideally, when I click the link to a tiddler in another wiki, I want my browser to open the tab that already has that wiki open, and then modify the address to …wiki#tiddlerIWant.
Any ideas?
