In the tag on placement mode:
I wish the tags would automatically be placed such that the angle of the text matched that of the duct.
The way it currently works has 2 deficiencies:
1) You only have 2 choices for duct angle
2) The angle of all ducts is set to whatever you manually set it to last.
When placing duct tags individually:
The text angle should not have to be predefined, it should be set automatically to match the duct angle.
