Hm... I like my current setup, but I may have to try that instead. Any chance you could elaborate on the settings it offers? Particularly with the image gallery, because I went through a bunch before settling on the one I have. How invasive are the descriptions of the photos, and how customizable is the lightbox?
Also, in terms of caching and performance, does it have more advanced options than the one in the screenshot you linked? I like all the different options W3 total cache gives me so that I can select which methods work well for my machine and enable/disable specific types. The screenshot only says "Speed up images and photos," if I'm not mistaken. Can you also customize it for page, object, minify, database, etc?
Also, in the screenshot you linked, it seems like VaultPress does the backups, and that it's paid. I'm not sure I'd be willing to pay for that if UpdraftPlus is free.
Also, what is infinite canvas?
Sorry to bombard you with questions. Trying to figure out what's optimal for my needs.
