Since the introduction of publishers and subscribers, it has always been difficult for the second developer to identify where these functions have been used in order to be able to make further adjustments or extensions if necessary. The "Event Subscriptions" window must always be filtered and searched to find the relevant code section. Here is my suggestion For publishers, in addition to the "Go to Definition", a "Go to Usage" function should be created, with the help of which developers can directly call the subscriber codeunits in which the publisher is used. If it is used only once, the system can call the code directly, if it is used several times, a corresponding selection window should appear. This extension is not necessary for subscribers, since you can see directly from the properties where they were used.
