[ Remark: This text was written before 28.9., it seems you have changed that behavior a little bit already, it reacts slightly different now in Safari, however, I think it’s still worth posting / reading / discussing]
a)
Sorry, I may not understand your concept, but:
When opening the editor there is a section on the left hand side used for file storage.
If anyone could save there it would be just a pile of sh**.
Call it rubbish, garbage, lost&found - but be aware that you would have hundreds of files there, in just some days, most of them unusable, incomplete, dangerous, faulty and even deliberately wrong.
=> Useless.
BTW even with logged in users such public files are nearly useless, people tend to start without any target / plan in mind and to fail at 10% of the work.
You have to know the user (skills + mindset) to get some ideas from their work.
So think about:
The first page is your business card, it’s easyEDA’s personality.
It will (re)present your product to the world, let it be a journalist, adversary, friend or user / customer.
Don’t let crap to be visible on your first page.
If there is a showcase, a display on your business card:
This extraordinary space belongs to the “Top of the Top”, specially selected items to show the capability of your product AND your community / user (group).
b)
The pull down menu reads “My Projects” but I also see “Anonymous Files”?
In contrast: “My Parts” and I see nothing? (although this would be correct now)
*?*?*?*?*
I don’t know enough about your concept, but what about:
A new pull down menu entry as “easyEDA featured content” on opening the editor?
Instead of garbage some folders like icons, schematics, PCB, contest, easyEDA news, …
and sometimes (?) some files to new features / development / tips & tricks
or special user contributed content
or a disabled folder (visible to public - but dimmed) with content for (paid) Gold Membership,
or …
?
