Hi Victor,
if it is mostly about having both applications running at the same time, and receiving log output for both, I would suggest running one application normally via Qt Creator, and only the one you are also actively developing on in that moment should run via the Live Client.
If you are trying to investigate a crash, the Qt Creator log output can provide more info that with the Live Server. Actually running it with the debugger in Qt Creator would be the best way of getting more info on a crash, as you can get a stack trace of the exception then.
If you want to provide us more info including a screenshot, you can also send your request to support@felgo.com
Best,
Alex
