Resolved 6 questions on Estate / SPProperty

Hello

I have a few problems to finish my site with Helix Ultimate + Estate :
1 - How can we sort the property features in properties setting (it doesn't take the order of the list in features admin)?
2 - Properties search module : how can we change the maximum number of persons/property to select (currently limited to 5 ) ?
3 - The search field in properties list in the SPProperty admin doesn't work. It doesn't select the properties containing the word entered. Why ?
4 - In SPProperty I made property features in english (duplicate the french feature + change the name and select language). But the images (as the icons don't work neither), working fine in french,are not displayed in frontend. To make it working, we have to select first the language for the user in admin (english if we want to select features in english). Normal ?

How can we change these 2 parameters for mobiles only :
5 - Number of columns in the properties list ?
6 - Width of each of the 2 columns at 100 or 95% (instead of 75/25% for desktop): property description on the left, and 3 modules on the right (price/agent/form) ?
Example :
.col-md-7 {
-ms-flex: 0 0 75%;
flex: 0 0 75%;
max-width: 75%;
}
