I am personally fine with storing that kind of information (tables and other structured documents) on other platforms, with links.
I do not intend to try to force DL to be everything for me. I don’t believe I can achieve that with any tool without compromising/sacrificing in a lot of other ways.
(I tried at first with Evernote - storage, task management, place to write content etc. but it became way too clunky).
Though a lot of tools overlap today (just look how many non-numbers things spreadsheets are used for today), there will always be tools that are best for their specific jobs.
As long as they can link well, that’s the most important.
One thing that could be considered though, if a lot of users like to have stuff like tables, spreadsheets etc. inside their DL landscape is to make it easier to IMBED such things.
Ie. just set up your sheets, tables, graphs etc. in your other tools and imbed them in a bullet so you and view and manipulate them.
