[Cuis-dev] How to stop the editor asking to delete a certain variable ?

[Nicola Mingotti]

Hi Hernan,

thank you for your directions, i will copy in my notes and study them
as soon as possible. Then of course, if it is a feature that more people
like let's make it global ;)

I agree about preferences, let's keep them at minimum as much as we can.

bye
Nicola
