With the recent changes there will be a lot of servers that enforce signatures. It would be nice if you have a warning or toggle to not accidentally send a signed message. This would remind you to use a chat alternative of choice.

You already have a warning in the form of safety status icon. What exactly you suggest beyond it?

Ah, I guess that icon didn't work for a few versions. You should be able to see it in 1.19.1-pre3-v1.4.2 though, near the bottom right of chat screen.

I know this is a month old necro but may I suggest that while connected to "whitelisted" servers, there be an option to still prevent sending messages clientside, or a prompt per-message option (e.g. doubletap enter with a hotbar prompt). This would allow users to use whitelistAllServers while staying relatively protected, as I'm sure the safety status icon, while enabled by default, will be missed due to bad habits and/or forgotten about during gameplay.

It's more complicated than that, because - how do we define "message"? Do we count commands as messages? If we do not, what do we do about /say and /msg? If we do, wouldn't it be annoying to go through all those double taps and such for every command? What about custom commands?

I don't want to make raising user awareness more invasive than it currently is. Playing on enforce-secure-profile servers is already inherently unsafe, and enabling whitelistAllServers option is, by extension, too. NCR is there to help and inform the user, but not to babysit them.
