Merge Tags Plugin?

[leeand00]

Merge tags plugin for tiddlywiki:

Synopsis:
You have a huge list of tags after you've finished entering
information into your wiki.
Many of them refer to the same thing, but they are different. In
this case you want to
merge these tags that refer to the same thing together so that
their tiddlers are all
filed under the same tag.

This is the problem I intend to solve with the Merge Tags Plugin
(yes I realize that there is already the rename tags plugin, but here
is what I am proposing as either a new plugin or as an addition to the
rename tags plugin)

For example:

Say I have the following tags which refer to the animal cat:

cat Cat Feline cats Cats

- Figure 1


Of course in real life I would have a bunch of other tags as well in
addition to the ones that refer to the animal cat:

cat dog Cat cow chicken Feline cats Cats animal

- Figure 2



Given these list of tags, I simply click each of the tags that refer
to a cat that apply (the clicked ones are in double quotes)

"cat" dog "Cat" cow chicken "Feline" "cats" "Cats" animal

- Figure 3




Now when one or more of these tags are clicked, below the list of tags
a dropdown (populated with a list of all clicked tags) appears

below the list of tags along with a button:

"cat" dog "Cat" cow chicken "Feline" "cats" "Cats" animal

merge to tag: |-----------| ------------------
| cat | | Merge tags |
| Cat | -----------------
| Feline |
| cats |
| Cats |
-----------
- Figure 4




The single tag which is selected in the dropdown box will then rename
all of the other tags in the tiddlers which were tagged with the items
selected in the list, thus reducing the number of tags in the wiki and
keeping it more organized.


merge to tag: |-----------| ----------------
| *cat* | | Merge tags |
| Cat | ----------------
| Feline |
| cats |
| Cats |
-----------
- Figure 5



For example suppose that the tag we choose to merge on was "cat", if
we had the following tiddlers before the merge:

|Tiddler 1|
|tags: Cat Feline animal |

|Tiddler 2|
|tags: cat animal |

|Tiddler 3|
|tags: Cats cat animal |


After selecting cat from the "merge to tag" dropdown and clicking the
"Merge tags" button, the tiddlers would be tagged as so:

|Tiddler 1|
|tags: cat animal |

|Tiddler 2|
|tags: cat animal |

|Tiddler 3|
|tags: cat animal |

Thus successfully merging the multiple tags with the same meaning into
one single tag, and cleaning up the tags in our wiki.

Please stop me before I start developing this if it already exists (or
if you are already working on it, so that maybe I could help), and let
me know what you think of the idea.

Thank you,
