Filter out application which are not in use

[jonaslagoni]

Describe the bug

In the ApplicationFocusView, it always shows external applications, regardless of whether the application interacts with it or not, but I don't think that gives any value to the user because why would you care about other applications you don't interact with? If you want a larger picture you would use SystemView.

So I would suggest we filter out all external applications which do not interact with the primary application.

The external application nodes are created here:

EDAVisualiser/library/src/visualiser/helpers/collect-nodes.ts

Line 96 in 19b7da7

if (external) {

This is also the location for filtering out applications if they have no correlating operations to the focused application.

I would suggest doing something along the lines of:

• Track all the channels that the primary application uses (in an array or map or similar)
• Dependant on how the external application is created (from AsyncAPI or core building blocks), we cross-reference against the above list to filter out any nodes that are irrelevant.

In case you have any questions or problems feel free to ping me here or on slack 🙂
