gitea/web_src/js/modules/toast.js

Lines 11 to 19 in f65977d

	warning: {
	icon: 'gitea-exclamation',
	background: 'var(--color-orange)',
	duration: -1, // requires dismissal to hide
	},
	error: {
	icon: 'gitea-exclamation',
	background: 'var(--color-red)',
	duration: -1, // requires dismissal to hide

duration is -1, so it will not disappear until user close it . 😕

Is it possible to check the content of the warning message, and if they are same then add (number) at the behind of the existing one?
