Some enhancements for Tags

[Duong Nguyen]

Some helpful features for me:

+ When move over a tag in Tags Browser, show full name of that tag in tooltip. Because I have hierarchical tags, and long tag name.

+ Support delete and rename for top of hierarchical tags in Tags Browser. Ex: I have tags A.B.C, A.D.E. rightclick on tag A can rename only A for two tags, or delete tag A will delete all subgroups of A.

+ Ability to add muti tags to Calibre database (pre-defined tags, button to add tags in Manager tags window) before used to add to books. When that, I can drag and drop book to a tag in Tags browser. Useful when I have a standard list of subjects like BISAC Subject Heading list at bisg.org, or catalogies like bookstores in hierarchical. I attached a BISAC Subject list 2012 file for everyone need it.

- I have a book , in Edit metadata , tag field show: COMPUTERS.Reference, COMPUTERS.Data Modeling & Design. When I add custom columm build from other columm. Then use template: {tags:sublist(0,1,\,)}
But it get COMPUTERS.Data Modeling & Design, not COMPUTERS.Reference . Seem it get first item by sort, not by order in tag field of Edit metadata.
I want make first tag(COMPUTERS.Reference) as main tag for Save to disk. How can I do that?

Can you help me implement above features?

Regarding:

+ Show the full tag name. Fix committed

+ Rename hierarchical tags: won't fix. The underlying mechanism operates on one item, and I don't want to change that.

+ "muti" tags: create an empty book with all the tags you want to predefine.

+ The order of items in a list is not guaranteed. If you want the list to be sorted before you extract the first element, use template program mode or general program mode and sort the list. For example, in template program mode you would use something like:
{tags:'sublist(list_sort($, 0, ','), 0 ,1 , ',')'}

In the tooltip, can you make the current item (when use mouseover or by keyboard) hightlight by set font style to Bold?

EX:

- With Tag: (tags: Phylosophy) -> when mouse over "Phylosophy" in Tag Browser , make "Phylosophy" in tooltip with Bold style.

- With hierachical tags: (#bisac_subject:ANTIQUES & COLLECTIBLES.Sports Cards.Baseball) ->when mouseover "Sports Cards", make only "Sports Cards" in tooltip with bold style (keep full name tooltip).

Thank you.

I am not interested in implementing either of these. You or someone else is welcome to do the work.
