Removing multiple tags
As we can add tags to several tasks by clicking right > "Add tags...", a good thing would be to be able to remove a tag from several tasks.
An option could be : "Remove tags..."
Izidor: There is already implementation in the development version of GTG. I changed "Add tags..." into "Modify tags..." where you can enter multiple tags to add or remove. If you put "!" before the name of a tag, GTG removes the tag from selected tasks. Another example: "!unix linux" removes the tag @unix and add the tag @linux to selected tasks. You can try the development version by using our GTG Daily PPA for Ubuntu or download the development version:
bzr branch lp:gtg cd gtg # to test GTG without messing with your data ./scripts/debug.sh
