Motivation

Undo is not available if needed. One reason is the small default number of undo steps.

User Scenarios

n/a

Goals

The perceived robustness of OOo's undo functionality is increased if undo is available in more cases.

Requirements and Dependencies

Requirements

A larger undo stack causes more memory requirements.

Technical Dependencies

<Are there any technical dependencies for this feature? Does the implementation of this feature create any technical dependencies to other program parts? Or very important any issues for automatedd GUI Testing?>

Competitive Analyses

StarOffice 7

The default number of undo steps is 20.

MS Word XP

The Options dialog of MS Word does not contain a setting for the number of undo steps to remember.

Adobe Photoshop 7

Photoshop has a setting for History States. The maximum is 1000 steps.

Detailed Specification

The default number of undo steps is 100.

The maximum is 999. (see MMP-2)

Future Tasks

MMP-2: Have a Undo Options spin field that can handle 4 digits. > OOoLater: i53096

MMP-1: Remove the limitation for the undo history at all.

Notes

NN-1 Concern. The performance of Calc might be too slow if the undo history is increased to 100 steps.
