That's certainly a good idea.

Wilcoxon tests aren't something that I use every day. And for a minute I was 
confused why "against" was optional. I think that sort of confusion could be 
avoided, if the "Location" parameter was included on the first tab. In fact, I 
think it might be a good idea to change the dialog in line with the new design 
of the t-test dialog.

Well, in the long term, it will certainly be a good idea to switch to actively 
maintained packages. In this case, the key difficulty seems to be that 
coin::wilcox_test assumes data in long format, instead of wide format. So the 
first step in that direction would be a generic (embeddable) plugin for 
conversion between wide and long...
