[bug] Cache domain-group mode settings

[TNET-feng]

Some features are not saved after restarting the app! For example, in the upper right corner, more middle, grouped by domain name. Restarting the app after setting it is still displayed in the list, and the settings before exiting are not saved

Thanks for feedback. I will add this into the cached config later.
