Apps enabled to work on Andromium OS

I want Andromium OS to let my sister to work in a unique device/computer. She will use it for browsing, editing images and videos, and creating slideshows from images. So I consider that Andromium + USB powered hub (+ USB HD + USB keyboard + USB mouse) + (Ezcast + VGA Monitor) + Google Apps (photo and video edit) will cover all her needs. But, nowadays, Andromium do not show all installed applications.

So, what applications will work in Andromium?

Thank you
