That works for me too, but is not an option. At least not a convenient
one. I think it's convenient to add things to (several) different
files rather than adding them into the script. My solution, at least
for now, seems to be replacing Zenity with Yad. Yad seems to use
pretty much the same syntax, so in many cases I only need to replace
the word ”zenity” with the word ”yad”, with only minor adjustments.
But it's good to know that this works, it could be a clue for the
developers.
