To compensate for @felix k's answer, rqt saves so-called perspective when it's run on rqt_gui and closed. (I just found that it's not documented) things that are saved include:
rqt_gui)rqt_gui's size and position with respect to the computer's desktopTo run rqt_gui, you just run:
$ rqt (Groovy and later)
$ rosrun rqt_gui rqt_gui (Fuerte)
Running rqt_gui is the recommended usage of rqt, although you can run each rqt plugin individually.
In response to the RViz example in your question, rqt_gui does NOT save the configuration of each plugins as I listed above; instead it's up to how each plugin is implemented. And the feature of rqt variant of Rviz, rqt_rviz, is the same with what RViz has, because rqt_rviz embeds RViz, which doesn't save the .config file that was used the last time (if I remember correctly). You can open an enhancement request here.
Actually every plugin can save its intrinsic state and restore it again. Some plugins store things like checked checkboxes and values of input fields. rqt_publisher e.g. restores the list of message types to be published to reuse the once setup publishers.
Every plugin can persist information through these two callbacks: https://github.com/ros-visualization/...
The rqt_rviz plugin would need to implement those order to store / restore information.
You can import and export perspectives via the Perspective menu.
Is there any reason for the the difference between in saving configuration in RVIZ and saving perspectives in RQT? RVIZ remembers which config file it was opened with and I can just ctrl-s to update it. On rqt, I need to export the perspective, selecting the file path again every time I do it.
Each plugin is responsible to store/restore its intrinsic state and most plugins do that correctly. If a specific plugin doesn't do that for you you might want to fill a ticket in the repository containing that rqt plugin.
