I develop a SharePoint solution and I need to update files everytime.
I find a solution for the files in the Site Assets library. I go on the library (or the list), I click on the ribbon, "Library" tab and "Synch" to synchronize the folder on my desktop :
After that, I can open the file in my favorite editor and when I save, the file is updated on the SharePoint Online.
The issue is, I can't do the same thing for the Site Pages library.
Any suggestions or reasons ?
