Questions/Suggestions

Can you have compilation errors give a link back to
the code in IDE like the changes log?

That's pretty difficult, given that there are many types of compilers (java, non-java) and even for java compilers there are some variations.

If a user does a Remote Run personal build from IDEA,
why don't those personal builds show to the user who
invoked them in the IDE once they are completed?

In IDEA there is My Changes tab, which shows both personal builds and ordinal commits.
When personal build is finished, user should get a popup-like notification in IDEA.

Is there a way to allow an Admin user to see all
Personal builds?

No, there is no way to do it so far. You can see all running builds (including personal ones) on the Agents page. You can also see pending personal builds in the build queue.

Kind regards,
