Hi narcispr,

if you launch rqt_gui when not all topics are being published yet, the plugins that depend on a topic will require you to set that topic again, but if you launch rqt_gui at the end, when everything is published, then your saved setup will keep track of the same topics.

1. First, open all nodes and rqt_gui and set it up as you like.

2. Then, close rqt_gui first, then all nodes.

3. When you need to work again, run first all nodes, then rqt_gui.

That works for me.
