Will the column limit be increased on Calc? It's 1024 only!

I have more than 3000 columns, and now downloading the MS Office 2007 :frowning:

Not in the near future, sorry.
See this bug for details:

Gnumeric handles way more columns and is free software.
Also, many use a database for such datasets.
