Different products have different interfaces and work differently. Microsoft Office, LibreOffice / Apache OpenOffice, IBM Lotus SmartSuite, Corel WordPerfect Office, NeoOffice, iWork, and other office suites all have different ways of exposing functionality to the user. I am dismayed that students at a school, that presumably go there to learn, are so easily “baffled.” Either the teachers or the students are not fulfilling their role effectively. The world is a diverse place. It contains lots of different things. The road to disappointment is paved with expectations.
To more directly answer the question, it is highly unlikely that a ribbon-esque toolbar interface (similar to that used by Microsoft Office 2007/2010/2013), will be created for LibreOffice. Since LO v4.1 a sidebar has been implemented, and since LO v4.2 this sidebar is exposed by default. A recent comment by Charles-H. Schulz (founding member and current director of The Document Foundation, which produces LibreOffice) on the Design mailing list, in relation to the sidebar, indicated:
I think the takeaway is that you don’t have to use the sidebar. It is redundant to other elements of the UI and is by no means no more modern than LibreOffice’s interface since it comes from Lotus. … we are NOT interested in becoming a [Microsoft] clone à la KingSoft.
Given the difficulty being faced by even the sidebar, a ribbon-esque toolbar would seem improbable, to say the least.
EDIT: It is evident from some of the “answers” below that members of this forum do not always fully comprehend that the MSO ribbon is patented (US8255828) UI technology. Other parties are free to license this technology but there are restrictions in certain cases e.g.,
2006-11-06, Microsoft News Center article:
The license is available for applications on any platform, except for applications that compete directly with the five Office applications that currently have the new UI (Microsoft Word, Excel, PowerPoint, Outlook and Access). We wanted to make the IP available broadly to partners because it has benefits to Microsoft and the Office Ecosystem. At the same time, we wanted to preserve the uniqueness of the Office UI for the core Office productivity components.
2006-11-21, MSDN Office User Interface blog post:
There’s only one limitation: if you are building a program which directly competes with Word, Excel, PowerPoint, Outlook, or Access (the Microsoft applications with the new UI), you can’t obtain the royalty-free license.
Why this exclusion?
Microsoft spent hundreds of millions of dollars on the research, design, and development of the new Office user interface.
So, I would strongly suggest to those wanting a ribbon UI in LO that they donate something. Probably a lot of something.
Update: In late 2015 Microsoft filed a lawsuit against Corel, makers of WordPerfect Office, over infringing the Ribbon UI. Details over on Softpedia and ZDNet.
