As a Roblox developer, it is currently impossible to make the new chat window taller, this means in roleplay oriented games or games with significant chat presence, players who are trying to navigate chat or read back a lot of history have to do so in a tiny uncomfortable window.
When switching from the old Lua chat, I wanted to add a button to my topbar to expand the new chat for users who used the old Lua chat’s resizing feature, but the HeightScale property on the ChatWindowConfiguration does absolutely nothing on larger screen resolutions, and is clamped at 2. I simply want to be able to toggle the chat window between a small version and a larger version.
If Roblox is able to address this issue, it would improve my development experience because I would be able to support more of my players’ needs with the chat window in my game.
