It is very difficult to read a microstation pen table. Figuring out what selectors are turned on/off, then having to change tabs to see what happens to the output.

Using a more readable and understanable query builder UI like many apps have adopted recently would be easier to create and maintain. Example of this style is the JQuery Query Build:

https://querybuilder.js.org

Each section would display it's selctors at the top, and what it does to the output below that.
