JeffOffice

JeffOffice is a free, open-source office suite, with four apps.

JeffPub lays out flyers, newsletters, brochures, business cards, and other
print pieces, with templates, mail merge, and PDF export. It opens and saves
.pub files.

JeffDeck makes slides and runs slide shows. It opens .pptx, .ppt, and .odp
presentations and saves .pptx and .odp.

JeffWrite (a preview) writes letters, reports, and other documents. It opens
.docx and .doc files and saves .docx.

JeffCrunch (a preview) makes spreadsheets. It opens .xlsx, .xls, .ods, and
.csv files and saves .xlsx.

The apps run as jeffoffice.jeffpub, jeffoffice.jeffdeck, jeffoffice.jeffwrite,
and jeffoffice.jeffcrunch, and each has its own entry in the application menu.

Files in your home folder open directly. For files on a USB drive or another
removable disk, allow access once with:
sudo snap connect jeffoffice:removable-media
Files elsewhere open through the file dialog. Printing goes through the
system's print service (the cups interface). If printing doesn't work, run
sudo snap connect jeffoffice:cups and try again; saving a PDF always works.
