I'll notice, that this theme is not new. Here are links to other topics: first link and second. So we researched this before.
The main Wialon advantage is flexibility. We separate sensors by their types and algorithms they are calculated. So you can use a digital sensor that has values "on/off" for a belt control, door control, cruising taxi control and much more. That is why we have a general column for any sensor. If we just add columns for more sensors we'll get something like on the attached picture. You see, that such a picture is not for comfortable control, as every color for every column can mean whatever.
But you see, that we have a column for battery sensor. It has its own icon and color scheme according to its value that is between 0 and 100%. We added it as it is a common sensor for many devices, it is essential for personal monitoring sphere.
So we cannot add just some columns. We can view some specific sensors. If they are common, control of their values solve some known problem, we may add them.
I recommend reviewing the possibility to control sensor values by notifications. Also, we have a tool for sensor control - the app Sensolator. Pay attention to it, please. Well configured Sensolator will be more comfortable then monitoring panel even after adding more columns.
