[Feature]: Limit index files to 1 per folder, by renaming them instead of creating new ones

[kemonprogrammer]

Appreciation

• Thanks so much for making this plug-in. This was exactly what I was looking for

Problem

• I created the indexed files, but I overlooked that the default prefix was "Index_of". So I deleted the prefix "Index_of" and pressed the button again and now I have more than 1 index files per folder, when only 1 is needed.

Feature

• Detect already exisiting index files (maybe by looking for files containing the foldername or looking through each file for a line with "%% Zoottelkeeper... %%")
• if the folder doesn't have one, create one with the new prefix
• and if the folder has one, rename them with the new prefix

Remarks

• If there is already such a functionality, that I overlooked, I would be happy to hear about it

Came in here to say this, Also if a name change to a folder the Index file inside will create a new index file as well. I recelty had four index files in about a dozen folders due to some changes I kept making on the prefix witout realizing it was generating new Index instead of updating existing.

Hi @kemonprogrammer hi @javathehunt ,

yes, this is the expected behaviour, but you convinced me that I over-worried the things about removing a file from the vault. I'll implement it.
