Jed, Thanks for clarifying this for all.
My Suggestion on a PWA is only because my own reading and someone else's post have talked about getting *reliable local storage* (if not still within the browser) for PWA's. The need for this continues to be something a lot of designers and developers want and there are suggestions that such reliable storage mechanisms may be made available soon (see below). As you say if reliable browser local storage becomes available across browsers we may be able to use this directly from Tiddlywiki, however it may only become available to PWA's or versions there of which include a config file containing resource needs. Other community members have suggested other limitations to Tiddlywiki's mechanisms that would prevent it from becoming a PWA itself. Thus the speculative idea of having an independant PWA saver, if reliable local storage becomes available, and only if reliable local storage becomes available. For example at this link we can see Safari and Edge do not have a cache eviction process thus browser local storage may be more reliable BrowserEviction Policy Chrome LRU once Chrome runs out of space Firefox LRU if the whole disk gets full Safari No eviction Edge No eviction The above was found here https://developers.google.com/web/fundamentals/instant-and-offline/web-storage/offline-for-pwa and includes a section; *Current and future offline storage work* *If offline storage interests you, the efforts below are worth keeping an eye on* Of course a PWA could be storing the data on a cloud service as well. I expect there may be limitations to one tab communicating with another tabs PWA's. Regards tony -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
