We do have an advanced config setup via raw commands /set <token> <value>
I implemented a new token to control this behavior and you can test it out in this new build.
1 .
Download FlashFXP 5.1 build 3846
2. Install the update
3. Commands > Raw Commands (or Ctrl+R) and enter
Code:
/set app.queue.parent 1
This setting is remembered on restart so you only have to do this once, to undo this setting
Code:
/set app.queue.parent 0
Please give it a try and let me know
