No, tip must be shown by default, it's a misconcept to hide it.

Have more option, something for "Select one" , and some other for dybamic tip : why not. But tip must be shown.

You can use template.css to hide the tips you want.

I also want this. I always write my own instructions and I have never used the tip function. It is annoying to have to turn it off for literally every single question I program.
Maybe you can have it as an option in the global settings for the administrator (that is, I can choose to have tips hidden by default)

I am also in favour of this, when needed, I write my own tip texts.

Could this be an option in the global survey configuration?

Show tips:
On/Off

Theme options ?
Seems to be a really good idea !

need more option too

1. Hidden when success (current situation)
2. Hidden always
3. Hidden always BUT : shown when user try to submit

See : https://gitlab.com/SondagesPro/SurveyThemes/skelvanilla/-/blob/master/css/skelvanilla.css#L194-200

and what for sq_fn_validation and q_fn_validation : a separate settings ?

Else : it's really a Question attribute linked with Theme : See 14248: Allow survey theme to add (and use) question attribute feature request
