The attached screenshots detail a minor, but fairly important change (at least usability-wise) to the startup dialog in KOffice-1.5 applications.
The first screenshot shows the current startup dialog in KWord-1.5.1 and the second one shows the same dialog with my proposed improvements.
The only difference between the first two is that in the latter one, the Open existing document... and Open this document buttons are much larger than in the current version.
The third screenshot displays the start-up dialog with the big Open existing document.. button at the top, as per gassauer's suggestion (thanks)
The reason for these proposals is that both of these buttons are used very often (in fact one of the buttons will probably be used every single time a KOffice application is opened), yet their size is diminutive in comparison to the other elements in the startup dialog.
This further makes them harder to find for the first time user and harder to hit for all users.
