Improve readability

[mjf]

Thanks for the nice tool! I would like to ask for few options to be added/improved:

• change font to monospace (toggle on/off?)
• change font size (+/-?)
• let us choose from combinations of ordering ordering of the 3 columns (e.g., I would prefare to have the first column rather on the right side and the message body in the middle the other two, etc.) and
• allow to resize the columns horizontally (the message body is too wide for fluent reading on my screen now)
• perhaps contrast is also a little suboptimal and could be improved somehow

I like the tool otherwise and will for sure use it.

I added a monospace font option in settings!
