When loading an *.sr file PV could show some additional information about the file somewhere (a small label or tooltip or whatever): - number of channels in this file (though this info is already there when you click the "channel config" icon, so this may not be needed) - samplerate of the logic data in this file - number of samples in this file (the total amount of time is visible from the scale bar, so that's not needed) Especially seeing the samplerate that was used for the file can be important for the user, since it can help evaluate whether running a certain PD on that data even has a chance to work.
In the meantime the CLI grew such a feature. The combination of -i and --show results in the output of this data. It's important to note that the details are _not_ taken from a file's header, instead "empty processing" is done as the input data passes by. Which makes the feature transparently work for any supported input file format.
