I looked at
https://giffmex.org/gifts/ideastew.html the original work. I have looked at it several times, but always feel it kind of work the opposite way of my brain. Don't let that worry you, I have felt that earlier with some of Davids work just for later to love and use it heavily. It all comes to the question are you working from top to bottom or from bottom up.
I think it is supposed to collect all the information in the Home tiddler (Default tiddler in ideastew.)
It might be an idea to save a copy and test it in the original how you like it and get to know it well. When you are sure it fits your way of working, and know how it works, it will be easier for you to know if it will fit with other changes you have done to your tiddlywiki.
I myself love Stroll
https://giffmex.org/stroll/stroll.html It can be used for a lot of things. David has made it easy for us to get the parts we want to use in other wikis. Still some things just do not go well with other plugins at least not without some changes.
I find that I have to try a wiki for some time, to get the feel of it. I do not find it easy to understand just from the description. (also it is quite fun. The tiddlers I created can always be exported and later imported into another wiki or dragged and dropped. It is only after having used my wiki for some time I start to know, what I need and what I would like. Still it changes over time - and all the time. ;-)
