Better way to increment multi-tags
Less of an issue and more of a improvement suggestion. Multi-tags are very convenient, but it can be a dull process to add a bunch of them, because if you want to use a specific range of tags, you have to click the green + button, and then manually editing the tag number on the field for each tag you add, since the button only adds new tags.
I thought that perhaps the old Tag Range could use an improvement to solve this, since it got a bit useless for me moving over to UZB, especially since it doesn't work for arguments, which some important linedef actions do use, so I made this little mockup to show what it could be like (Maybe there are better ways this could be improved, like inside the actual map element window that you want to add the tags, instead of a separate action).
.. Unless there is already a way to do exactly that and I just don't know yet. Maybe a UDBScript can do this, but it would be useful to have this as an editor feature anyway.
