I was using a mod called "ChatCalc". Its basicly allows you to perfrom some calculations ingame, without using a calculator app. But, it doesn't work with your mod.

The problem is, when I wrote 2+2, i need to press "TAB" to see the results. With your mod, when I press tab, nothing happens.

The version of your mod: AdvancedChat-3.0.4-1.16.5

Thanks in advance.

Too bad that mod isn't open source! I'm planning on adding a custom command completer (I guess message completer now?) that people can interface into. If I get that working this should be not too hard. I'll look into it.

I'm not very good at programming, but it would be great if you could bring an option to your mod to make in-game calculations. Also thanks for your quick response!

I created a Feature Request for easier tracking and historical purposes. #60

Will be added in next update (time tbd)
