The usability of sharing entire categories with ##mirror directives could be improved by allowing to refer to a category by name. Currently the only way of referring to a category is by some large opaque number:


##mirror:cat=123456789


The only way to obtain this magic number seems to be the following:
1. Right-click the category that you wish to share in the Category list in the Transfers window and choose Share > In Channels.
2. Go to the Share window and click Edit.
3. Find the new ##mirror:cat= directive at the bottom and copy-paste it to its final place in the share list you want it to be in.

This could be significantly simplified to just writing the category name instead of the category number, like this:


##mirror:cat=mycategory
##mirror:cat="my category with spaces and \"quotes\""


Also, I see no real reason to use the cat= syntax for referring to categories. Why not just write:


##mirror:mycategory
##mirror:"my category with spaces and \"quotes\""


+1 for this

we all know there are many ways in which we can easily add something into the shares list, but some people just like to type stuff (I know I do).
