My issue with the current exclude option is that sometimes there are cases when you wanna link to a page in certain contexts but not others. Like how Wikipedia will link to a page the first time it's mentioned in another page but not subsequent mentions. Or like a list where you want every item to be a link but don't want to have casual mentions of list items to link to pages.
As for suggestions, some sort of tagging system would be amazing since stuff can often technically fit into more than one category and tags would be a good way to handle that. A way of exporting worlds to html or pdf would also be great.
Also I haven't seen the existing categories pop up when I clock on the category textbox. Might be a glitch?
Edit: Oh shit I didn't see the part about needing to right click never mind.
