Edit tags and properties quicker access in Tags mode

[danbalogh]

The list of tags in Tags mode has a bin icon for deleting tags, but to edit a tag or to edit its properties, I need to first select a tag and then use the menu icon way out in the corner. There is plenty of blank space in the rows of the tag list - would it be possible to add an "Edit Tag" and an "Edit PropertiesŰ" icon or command to each row, next to the bin?

In fact, an icon/command to jump straight to a query for all instances of a particular tag would also be nice in the tags list.
