MightyText for tablets on android

I've been using MightyText for a while now, it's an app you install on your phone and register with, it then sends your SMS to their servers and you can login to your account from your browser and send/receive messages.
It works really well, just does what it's supposed to, and despite that meaning 'they' have a copy of all your text messages, it's a great idea and I use it regularly to type a message from my computer instead of phone screen.

Therefore when I needed an app for my tablet I went for MightyText for tablets, thinking this is great, an app for the tablet that will work the same, let me send and receive. However, everytime I tried to use it, you couldn't see the messages as the screen was so cluttered:

This is the popup window that appears when a message comes in. The text of the message is missing, it should appear below the time and above the "Type message" prompt, but due to the screen being in landscape orientation it appears like that.

If you then open MightyText itself you see messages, but again not much room:

You can make the message out this time, but only the first line of it. If you then go to reply the keyboard then squeezes the screen so none of the message is visible.

This initially just looks like how the dialogues are generated and perhaps the font/text being used. I therefore contacted MightyText about it:

    Hi, the view on the tablet app causes messages to not be visible due to a
    very small message window due to all the other dialogues.
    I've attached a couple of photos showing both the popup message alert and
    the main window.
    Please can advise how to fix this display problem?

And I got a reply from their tech support:

Sorry to hear that. Just confirming, is your Tablet in landscape mode when you 
see this issue?

Which I confirmed, and I then received this reply:

Got it, this is currently the expected behavior. We may change this in the future.

So that's it, basically they know this, they do it on purpose (Expected behaviour?) and that they aren't really doing anything about it.

Really disappointing this, so I'm on the lookout for a similar app that will work correctly on my tablet screen.
