Adding an alert or dialog library

[SteinerPascal]

Hi have you guys ever thought about any kind of dialog library to interract with the user? For example to signal input validation or show connectivity errors?

Example: user inputs a data into the datewidget in which the startDate is bigger then the endDate. Dialog informs the user that this doesn't make sense. User (hopefully) enters a reasonable date selection.

something like this could be nice: https://github.com/marcelodolza/iziToast
