WPS Office, formerly known as Kingsoft Office, is an office suite for Windows, Linux, Android and iOS, that includes three components: WPS Writer, WPS Presentation and WPS Spreadsheet. The suite is compatible with Microsoft Office formats PPT, PPTX, DOC, DOCX, XLS and XLSX, for both reading and writing.
While the Windows, Android and iOS versions are offered for download on wps.com, operated by Kingsoft, a Chinese software company, the Linux version has a separate website (wps-community), and appears to have different developers: "WPS Community team is a small group working to develop the Linux edition of WPS Office".
WPS Office 11.1.0.8372 (2019) for Linux includes support for high resolution screens, and customizable appearance. From the application settings you can currently choose from 2 skins (2019dark and 2019white), or customize the WPS Office appearance by specifying your own custom background color, image and font size. Also, with the addition of skins, the WPS Office default icons changed in this release.
