Describe the bug
There doesn't appear to be a way to change the font size of tabs used for whispers. Even with the Font module enabled, the only options there are for the normal chat tabs. Whisper tabs do not show there.

There also doesn't appear to be a way to set a default font size for any newly created tab which would be helpful for this as well.

Related issues with no resolution: #60 #116

To Reproduce
Steps to reproduce the behavior:

1. Ensure the "New Whispers" setting in WoW's Options -> Social section is set to "New Tab"
2. Ensure the font size for your existing tabs is set to something other than the default of 12 (e.g. 14) using Prat's Font module
3. Whisper another player to open a new whisper tab and note that the font size in the new whisper tab is the default size of 12
4. Open Prat's Font module options again and note that there is no entry for the new whisper window, nor any setting for whisper font size in general.

Expected behavior
There should be a way of setting the font size for whisper windows

Fixed now - that was quick.

I was reading the diff and noticed it, haven't tested in-game yet though

I've added an option for this to the latest alpha (available on Curseforge when it finishes processing)

Amazing, thank you!

I did notice you left behind a DevTools_Dump call in FCF_SetChatWindowFontSize though =)

Confirmed working. Thanks =)
