I was fine with the change. Search actually worked. 

Having everything in one column may seem like it's good for a fishing sea and player use but in terms of pressing or interacting with the device.  It's now longer. 

If I would have tried to explain think of buttons pressed as same as scrolling. How many times do you need to scroll down to get to the bit of information you want versus when you have the tabs you only needed to click one button for each category. You wish to get to. 

So the previous version was far more optimized to get to any section of the monster with one person a button. Almost no need to scroll. If you did you needed to scroll once. 

And if the monster didn't even have any descriptions some need even less. 

With this new change everything is just plastered there not very neatly or pleasing to the eyes. 

And the bigger more complicated creatures are much longer. To scroll through. 

At the end of the day the only real benefit I see here. 

Reading between the lines is that this is the cut cost.
