Version: 1.6.1 (using KDE KDE 3.5.5) Installed from: Debian testing/unstable Packages I miss the "row/column groups" feature, available both on Excell aln OO Calc --under the "data" menu--. This is the functionality to define a set of rows or columns as a group, that shows a tree over/beside the table, allowing you to expand/colapse the group, givin a fast access to show/hide. This is particularly usefull with long sets of calculations involving an initial state, finally the end state and in between sets of intermediate calculations that can be of interest, according with the thing you're looking after. With the versión of kspread I use, If I ope a file with groups defined on it, the involved rows seems to be obliterated from the table, not giving any chance to use them.
Current kspread at least loads rows or columns that are inside groups; it doesn't yet do anything with the group functionality though
