I don't disagree with you, however someone needs to take up the challenge. Perhaps by creating a base that can be plugged into more easily than LibreOffice or Excel would help encourage development by the community (much like atom and its plugins)

Basically, I'm not happy with the status quo that we have no real alternative to Excel on Linux.

There is no alternative to excel period.

Its like dwarf fortress or bloomberg terminals - when you are digging through what you thought was cruft, you'll suddenly find an entire project/application worth of material to handle a feature you never thought you would use.

Except that feature is used by someone else everyday.

That's a nice idea. Libreoffice is rather difficult to extend.
