I have a spreadsheet called Planning with several sheets inside the file. Today when opening it I noticed my sheet tabs were missing. I have ones for budget, checkbook, birthdays, etc.
To go to another sheet I have to use the navigator box, and would rather have the tabs back. I can't seem to find the switch I must have thrown to an on position during my last edit. Is anyone aware of how to turn the tabs on and off? I tried using Tools - Options - LibreOffice Calc - View and turn on and off and on the view tabs. But that didn't seem to help.
Thank you for your time in reading. 
Well fixed it myself, reviewed all the help, and went to their website, to no avail.
But, found out that sometimes the tabs get hidden, at least on my machine with LiberOffice and Gnome. I had other spreadsheets show one or two tabs when I left all of them visible. I tried pointing at the bottom arrows was able to expand the tabs, none were showing. I hope this might help another who goes what-the-heck as I did, and find out that all is there, just a quirk of LiberOffice.
Sottry to any readers who wasted their time in review. Have a great day.
