Not a troubleshoot, but quite annoying in category params copy

Hi everybody (Hi Georges
For the record, i work often like this : i create all my categories, set up one category and copy then all parameters on the others categories.
I use the function "copy parameters" button in the category and now, the selector is like all the others on the site : you search and you click to fill the box.
Yes, but this is less usefull compared to the previous way to select : before, when i want to select all my categories, i click on the first one and Shift-the last one, all my categories was selected in 2 clics. Now, i have to clic on each category...
And if you don't have many categories, that's not a problem, but when you have "a lot", that's become tricky !
To show you, take a look to this screenshot

Is there a way to select all categories in 2 clics like before ? Maybe i didn't find the trick...
Thanks !

Hello

maybe provide a button or checkbox to (instantly) disable select2 JS ?
and display the browser based select

I also agree with a simpler method to select several categories at the same time, like a simple html list with attribute „multiple“ as option.

Other issue: If I move cursor over already selected categories (greyed in dropdown) the list is always closing.

yep : on my side, if i go on a already select element (grey line), the list jump on the top...

but for the record : it is "working" even if that's not very friendly for "big selection"
