Maybe there's already some way to do this, or some reason not to do this, but my understanding is that, presently, if you are looking at a position, and you want to add a new argument for the position, then in the bottom left, in the argument box, you can click "new," and this brings up a helpful dialogue where you can enter some information, plus it has lots of stuff filled out automatically.
Meanwhile, if you are looking at an argument, and you want to add a new counterargument for the argument, then at the bottom, in the "counterarguments" tab, you can click "new." But instead of bringing up the helpful dialogue, it just creates a new empty argument to manually fill out.
I think it would be faster if I could make the counterargument the same way I make the argument, and so it would be nice to have that dialogue box. I might be wrong, but it seems like if the dialogue box is useful for arguments, it's just as useful for counterarguments.
Good suggestion, and I think it is doable. But the naming options will probably need to be changed so some GUI design work will be needed. I'll try to get it done for the next release.
Development and testing for this new feature is complete. It will be included in the next release.
