1) I can't find any reference to it but I  think this feature is either not supported in Projects offline mode in the Desktop Client or maybe the 88 version of Chrome is too old (though I'm not sure how you update it in the Desktop Client). 2) Sorry but you cannot forward annotate unsaved schematic changes into the PCB.

When I make changes to the schematic and then update the PCB sometimes it results in major PCB revisions often undoing my manual PCB adjustments. Occasionally, I decide that my change is not worth the effort and I want to undo things, and that's what this question is about. I'm beginning to think I should be using the online version because that seems to have better capability. I chose the Desktop version thinking it would be faster. Any opinions on which type I should use (online or Desktop)? Which is more popular? Thanks, Frank <br> <br> <br> <br>

"When I make changes to the schematic and then update the PCB sometimes it results in major PCB revisions often undoing my manual PCB adjustments." The schematic is the master document in EasyEDA. Start with a complete, fully annotated (footprints, supplier info, part numbers, etc.) schematic, checked against the essential checklist and only then covert it to PCB. Any changes needed to connectivity or Footprints must be done in the schematic, checked then passed in to the PCB using Update PCB. Routing and placements can be changed in the PCB but do not change connectivity or Footprints in the PCB. That is a recipie for disaster.  I cannot advise on web vs. Desktop versions as I mostly use the web based version.

@andyfierman Thank you. I'm trying the online version now and now see the "Backup Project" option. Unfortunately, it only allows backup once a day and that's probably to slow for my fallback needs. OTOH, the Document Recovery Recovery option seems to work better than the Desktop version, so maybe this handles my fallback issues. Although it's possible, as a new user, any confusion might be on my part. Anyway, I think the Online version looks promising. BTW, again maybe it's my fault, but I'm having a tough time finding seemly simple setting/controls, and questions.. Like changing measurement units to inches. I would think this would be easy to lookup, but I struggled for a while before eventually finding it under View. In general, I do searches of the forums and documents, but I'm wondering if there is a better way? Thanks, again, Frank

As suggested in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)<br> <br> the native search tools in EasyEDA are not great so you can try to do web searches (using Google and Bing) prefixed with "EasyEDA". This often turns up stuff that the native searches miss. Units are set in the upper right hand panel in the PCB Editor canvas. You can always right-click > download a zipped project to your local storage as an additional backup.

@andyfierman , Hmmm,  the units setting as you describe was right under my nose...  Maybe I've lost a step or two as I approach my 80th birthday. I was using Google exactly as you describe, but 99% of the hits were on the EasyEDA Web pages so I subconsciously began using the native EasyEDA search feature. I see now using your Google technique would also have quickly answered my units setting question. Thank you. Frank P.S. love the download suggestion (quick and easy).
