Is your feature request related to a problem?

It's frustrating to have to deal with each one of these manually

Describe the solution you'd like

It would be nice if POB had standard multiselect functionality.

Standard OS-level functionality would be nice: click and hold Shift to select consecutive items, and hold down Control to select individual items.

Describe alternatives you've considered

n/a

Additional context

If you wanted to get fancier, you could experiment with a Gmail-style checkbox UI and have a star/favorite functionality, but I think that is more than what people would want, and I assume it would take longer to implement.

L’issue ne nomme ni fichiers ni tests ; commencez par localiser l’écran de sélection des builds et le point d’entrée de la gestion des entrées dans l’application Lua. Vérifiez comment l’état de la sélection est représenté, puis confirmez que, sous Windows, il est possible de sélectionner des éléments consécutifs avec Shift et des éléments individuels avec Control.
