Unique AppPrefs for different html files

[tyctor]

Hi

I have two html reports, one with all history stats.html and one for today today-stats.html (generated with --keep-last=1)
I want to have different panels displayed on each report byt default, but settings in localStorage use same key name AppPrefs, so i t is common for both reports
Should be possible to add some prefix for localStorage to have AppPrefs separate for each report? but probable there is some more behind, and only separated AppPrefs wont be enough.
