Hi Thomas
not sure what an undoer would do here? maybe delete the file? There is
no leo-relevant action here (yet)
I'm well aware I don't *need* the main(), but I prefer to write this way.
Same as with bash scripts etc. It helps for future modularity, I find. Of
course, 'YAGNI', but still. f course you are right that main() could be
more descriptive, this is only a POC.
The tricky bit is deciding where to store the clipboard files. Obsidian has
a special action when you click on inserted 'snippet' images; it just
stores the filename in the 'body', and uses its knowledge of where the
snippets are located when you do the equivalent of CTRL-click on the URL
Linking the location of the 'snippets' to the leo file and/or node is an
interesting challenge...
