Hello Biiird Studio

Thank you for your purchase, and for your suggestion. I will forward it to our development team for review.

In the mean-time, you can add this custom script that will stop users from navigating away from the page:

<script>"use strict";
(() => {
const modified_inputs = new Set;
const defaultValue = "defaultValue";
// store default values
addEventListener("beforeinput", (evt) => {
    const target = evt.target;
    if (!(defaultValue in target || defaultValue in target.dataset)) {
        target.dataset[defaultValue] = ("" + (target.value || target.textContent)).trim();
    }
});
// detect input modifications
addEventListener("input", (evt) => {
    const target = evt.target;
    let original;
    if (defaultValue in target) {
        original = target[defaultValue];
    } else {
        original = target.dataset[defaultValue];
    }
    if (original !== ("" + (target.value || target.textContent)).trim()) {
        if (!modified_inputs.has(target)) {
            modified_inputs.add(target);
        }
    } else if (modified_inputs.has(target)) {
        modified_inputs.delete(target);
    }
});
addEventListener("beforeunload", (evt) => {
    if (modified_inputs.size) {
        const unsaved_changes_warning = "Changes you made may not be saved.";
        evt.returnValue = unsaved_changes_warning;
        return unsaved_changes_warning;
    }
});
})();</script>

Hi again Biiird Studio

That will be forwarded to our development team, thanks.

Unfortunately, this custom script was shared with us by one of our customers, and it worked great for them. It may require some modification, but that is custom work, and is not included in the provided support for the plugin.

You can also check a few other solutions in the mean-time on this link.

Actually, you can add this (much simpler script), and it should work:

<script>window.onbeforeunload = function() {
   return "Do you really want to leave our brilliant application?";
};
</script>

This actually returns a warning like this:

But you can take a look at this link, there are some comments that mention how you can change the text in that warning.

Hello again Biiird Studio

Your suggestion has been forwarded to our development team.

Hopefully, they'll see it as an improvement that should be included sooner rather than later.

Hello again Biiird Studio

That's not a bug actually. That's how the plugin works at the moment. Like I said a few times already - your suggestion has been forwarded to our development team.

We don't develop new features of the plugin based on one customer's request, unfortunately. We receive a lot of suggestions like this, and they are stored in our "ideas" list. More times some idea receives a vote from a customer, more likely it will be developed sooner. Since you're the only one asking for this to be implemented (at the moment), it is not high up that list, so I can't say when it will be added.
