Those that see LibreOffice always ask me the same question: yeah that's nice but it doesn't look ready for prime time.
Things I use for LO for at my workplace
- Project and overview documents (todo list, big picture details, etc.)
- Very large text documents (hundreds of pages) since Word has a tendency to freak out on extremely large docs
- Initial draft documents (since moving to Word is seamless)
- Most conversions - whether from rich text or graphics programs
- HTML edits - including my home page and work with Markdown and Confluence docs
- Basic PDF edits - usually minor edits to a sentence or something needs to be deleted.
- Basic spreadsheets - I prefer their spreadsheet program sometimes as Excel can be overwhelming
- Print outs - printing out things or setting up PDF files where I want the layout to look a specific way (an alternative to Microsoft Publisher)
- Fixing bad or misbehaving MS Office files
- HOWTO files that involve pictures because drag-and-drop image stuff doesn't work efficiently. I generally use Word here.
- Track changes, collaboration - It might be great but as I'm the only one at my place of business using LibreOffice right now, I can't test this.
- Presentations and flowcharts - I do love PowerPoint and Impress just doesn't have the same level of usability. I dislike Visio for many reasons.
- Complex / Formatted Spreadsheets - Calc is improving but a lot of making data digestible is making it pretty and Excel remains my go-to program here.
