Why doesn't Lightroom (Cloud based) have a "save" option

[DMCProductions]

Although lightroom (cloud based) is a great program, it has one massive flaw.  You can't manually save your work! Please add in the basic File -> Save option to save your work.  I spent a ton of time working on edits only to have it crash.  Turns out, when lightroom crashes, none of your work is saved.  There is also no backups folder or way to retrieve something that the cloud had saved.  I understand its supposed to save to the cloud but in almost every situation ive had where the program crashes (which happens alot), it does not save.  Please add in the basic option to save your work.  Please fix this!

The way I deal with that issue, i.e. working for a long time editing a single image, is to periodically switch to another image then switch back to the original image. That's because Lightroom does not sync the current edits until that image is no longer active, so switching away from it lets Lightroom sync the stored edits to the cloud. 

Perhaps a bigger issue would be to find the cause of your frequent crashes, as I never encounter those and I have Lightroom active almost every day.
