PerceptiLabs makes good use of the browser's database/cache.

However, when it is necessary to use PL with an "empty" or null/initialised cache (e.g. to establish a known PL state & initialisation actions for fault finding, or robustness checking, or...) it is necessary either to use a private/incognito browser window (with independent cache)or to clear the existing cache, which requires careful control if other sites, etc. are not to be unintentionally affected.

It would therefore be very useful if PL offered a single button control so reset its data structures in the browser cache; the user should of course be required to confirm the action after being presented with a warning that resetting could take some time and that PL might not be usable until e.g. (current experience on V0.13.9) pre-processing of all data has been run again.

If the PL internal architecture would permit selective clearing of browser data structures per model/project that would be even better - as long as the user also has an option to reset all.
