Taking a look at what you saw on MSDN I can see how you found it wanting. I looked and saw nothing in the Operators, but if you click on the tree control on the left side, it expands and there is additional information as you drill down. For example, the Arithmetic Operators ... is one of the subheadings (with no real content either), but if you drill down again by clicking on - Subtract you get the following information:

Subtracts two numbers. This arithmetic subtraction operator can also subtract a number, in days, from a date.

That's a trivial example, but I think most of the details are actually there. The challenge is navigating the site to find what you want.

I'm also curious what UI controls you would like to have that are not available? The use of a web based interface does impose some limitations compared to what you can do with a regular Access application because you are limited to the use of macros at this point. Thus the power of a fully programable user interface that you get using VBA isn't available.

Addendum

After some further research, it turns out there are a number of sample applications that are available to study. In order to access them you need to be logged into Office 365, and you want to go to the Microsoft Store. Then choose the "SharePoint" store, and there search on Access - you will find several in the results that are what you are looking for, and in general they are free. There is also one that you can find by searching for Computer (it isn't indexed as being Access), and you should find a Computer tracking app that is pretty complete.
