Mario,

I hope this is the appropriate thread?

I believe you already have the skills we need to use the local storage and 
save changes process I proposed elsewhere.

   - If I go to a site with the local storage plugin installed, not using 
   auto save, make it so the only way to reset the dirty flag, thus leave the 
   website tab is clicking a "logout" process. Thus logout process would (if 
   possible silently) save the changes with the following filter 
   [haschanged[]] [enlist{$:/temp/BrowserStorage/Log}] !readme.txt 
   - This save would in fact be a download to a download folder only. See 
   below for a download folder name. This is like your backup solution?
   - Then if this save can occur silently, like the backup solution you 
   have already designed (I think), the user keeps using the URL to get to the 
   site and uses local storage, to close the browser or tab they must use the 
   logout process (Which could look like the current save button).
   - If we can save silently it would not be as intrusive if the changes 
   backup need only occur when closing the tab or browser.
   - Then a mechaisium to detect either first visit (no changes saved yet) 
   or the possibly rare case of lost browser storage, where the user can 
   create a new "backup changes" or restore the last saved changes.
   - The value being all saves can be in the download folder or below, 
   perhaps a folder based on the url such that the folder will be unique to a 
   url, as is the local storage. That is the name determine where the changes 
   are saved, so if lost the previous save can be found.
   - A separate download of the whole wiki plus changes (the default save) 
   would be needed to move to another save mechanism, local copy or to access 
   in another browser., or another machine. 
      - If browsers share the download folder perhaps you can change 
      browsers on the same machine?
      - We could have a "full backup" method, similar to the download, as 
      well, to restore the whole wiki, even a new one at a public or private 
url.
   


Notes:

   - Perhaps cookies are less prone to loss than local storage, perhaps a 
   cookie could store the backup folder/filename? If not present on current 
   url/wiki prompt to load from downloads?
