@Graechan @GnuTux
In 2 days you both and Fencepost stumbled repeatedly against the same obstacle of dialogues size , and that also caused some delusions in who installed but could not use the scripts
Now is possible that a limit not of scheme but of the gimp implementation that use the same GUI definition from 2004 (From then were several changes regarding script fu but none regarding its GUI )
Now are excellent reasons to not change what is simple and works well ...
Till works well !!.... now we are stumbling more and more often on the same obstacle
I imagine the solution simple as add to the possible UI definitions "v-sep":
"v-sep" stand for Vertical Separator, it is simple as a vertical line , the utility of the Vertical Separator is create 2 columns instead then 1 , and so
double the space available for the controls It is not as asking support for preview, or radio button, but only for a vertical line , it seems a more then resonable enhancement request for Bugzilla and the dev list
I believe was Kevin Cozens the developer behind script fu implementation and its updates , he mayfor h even better solution
suppose he still follow gimp mailist, and his site dedicated to script and tiny fu and gimp is
http://www.ve3syb.ca/software/tiny-fu/ (last update in the 2011 but were no relevant changes after )
I think may be a reasonable enhancement request
