Please add the feature to zoom increase and decrease the size of the font (text) in a chat window, so that those of us with limited sight can text with less eyestrain.

The feature should be initiated by sliding the thumbs away from the center of the screen to zoom increase or towards the center of the screen to zoom decrease.

Sometimes, the font size options you have in the app, just aren't big enough to read with ease.

Hope you will implement this new feature soon.

Thanks,
Christy
