It would be good if you can click on a item in the log, and it will take you to the code that created that event in the log. Similar to what has been done in B4A/B4i.
B4x IDEs share over 95% of their specs.
If you have a feature working on B4a, usually in the next iteration of any other IDE it will also be available.
It was not included. B4J logs system is different. Unlike in B4A and B4i where the logs are (almost) only consumed by the IDE, this is not the case in B4J. This means that in order to add this feature as well as other features, B4J needs to include two types of logs. It will be added at some point but not in the upcoming version.
