The first sentence in the second paragraph of the Welcome Screen text has some errors, mainly in punctuation.
Currently it reads:
"Linux Lite aims to provide each user with a basic collection of everyday tools, a web browser, email client, media player an Office suite an image editor and so on."
It should read:
"Linux Lite aims to provide each user with a basic collection of everyday tools: a web browser, an email client, a media player, an office suite, an image editor, and so on."
The most important changes are the colon after "tools" (signifying a list to follow), the addition of a comma after "media player", and adding consistency to the issue of whether to have an indefinite article ("a" / "an") in front of each list item.
A bit more debatable is the question of whether to capitalize the word "office" - in the replacement text I provide above I removed it because the phrase "office suite" is not a proper noun the way "Microsoft Office" or "GNOME Office" is. (LibreOffice is not a phrase, just a single word in camelcase.)
More debatable (and in fact divisive among grammar nerds) is the issue of the serial comma: whether to have a comma after the second-to-last item in a list of three or more; the item just before the "and" (or sometimes "or"). The majority of official style guides (including MLA, Chicago Manual of Style, Strunk & White, and APA) say to include that comma, so I added it in my replacement text above (where it comes after "image editor").
While I can post suggestions, I don't know how actually to fix the Welcome Screen text myself, so I invite and request whoever can to do so.
