You should switch to the Real Original SCID.
The game list is much improved.
To resize, you can just click and drag the divider between any two columns.
You can click and drag any column to rearrange the display.
You can click the headers to sort ascending or descending and for multiple sort keys.
The Original SCID is just better.
Download and see for yourself.
I've been playing with SCID vs PC but seem to have run into minor problems. When opening the game list, I can't seem to adjust or reorder the headings. The help files online tell me to right click on the column heading to change the width of the column or reorder the variables. But when I right click nothing happens. However, left clicking on it resorts the game list for that variable as it was supposed to.
What am I doing wrong?
