Good idea.
As a side note, an alternative way to add the ! would be to use a search and replace:
- search for: [[
- replace with: ![[
This is assuming the list of links from the search results copied to the clipboard were pasted into a note without other links or transclusions.
As another side note, I made a request a while back that is somewhat relevant here although it is not specifically about exporting or tags (so, I guess loosely related): Note Combo-Linker
Thanks.
