Auto-reload custom timeseries when changing new file

[ndepal]

In my workflow I load new log files (usually .ulg) frequently, going back and forth between logs.

I have set up a bunch of custom time series that I want to look at for each log. Currently, the custom time series are not updated with the new input data automatically.

When I open a new log file, I have to say "No" to the pop up asking me if I want to delete the custom time series, then click on each individual time series on the bottom left, click on the edit button, and click "Modify Timeseries" without making any changes. This is tedious if there are many custom timeseries and/or I need to switch between log files regularly.

It would be great if each custom timeseries was re-computed automatically when the user answers "No" to deleting them when opening a new file.

As a workaround for this case I use layouts xml files, that I duplicate and manually change filename for the previouslyLoaded_Datafiles and then load them in PlotJuggler.

But there is another not very good thing/bug - on layout saving customMathEquations list get saved in different order without respecting custom timeseries dependent on each other. For example functions heading and yaw makes deg from rad and then there is another function yaw-heading that use result of both previous timeseries. On layout saving PlotJuggler saves yaw-heading function first in customMathEquations section and only then yaw and heading. After loading this file again PlotJuggler complains "Invalid channel name" because it doesn't now what is $$yaw$$ and $$heading$$.

So I would not recommend to use custom timeseries in such way, better copy paste code and use self-sufficient functions.
