@TW_Tones ¹, my comment is still a question, but anyhow I hope you can take it as a kind of feedback 
What strategie to handle overwritten shadow and core tiddlers is recommended and practicable?
¹ I’m referring to this thread
Just a general comment. There are many threads sequestered from poverty - #8 by TW_Tones
I did move this question into its own thread.
I add a personal tag “Modified TW” on them. I use my tag to find an artifact created by myself once a time.
I’ve been thinking quite a lot about this topic recently. I rely on these two tiddlers: ModifiedShadowTiddlers.json (404 Bytes)
ModifiedShadowTimeline.json (725 Bytes)
ModifiedShadowTiddlers is an alphabetical list of all tiddlers, and ModifiedShadowTimeline shows the modified shadow tiddlers in a timeline view, which I use to see at a glance what shadow tiddlers have been changed.
In general, it is better not to edit the core tiddlers, but instead duplicate their function into a separate tiddler and tag the tiddler accordingly, then remove the tag from the shadow tiddler you are replicating.
@Vingolf unfortunately I have no idea what you mean, and what feedback I am supposed to get here.
Unfortunately @Mario 's moving this to its own thread seems to make the issue more complex. But solvable.
So I followed the link to the thread @Vingolf then followed my link to How to Quickly upgrade your single file wikis on Windows where mario has split it to this thread. Note I just renamed the upgrade thread to # How to Quickly upgrade your single file wikis in Browser due to a question there.
My assumption is Mario has moved dealing with overwritten shadow tiddlers to its own thread so it does not complicate the Upgrade Instruction’s. I too have suggested twmat do something similar.
