My thoughts on a tool trough is that it would come in handy for the way my work progresses.
Usually a piece is cut and then the ends are cleaned up on the shooting board. This keeps all the tools used close at hand.
If all the pieces were cut first and then cleaned up, it would be prudent to use a tool put it away and move on to the next step. This method is used sometimes when making a lot of similar pieces.
It is all in the manner of how one does their projects. In a batch process method, a tool tray may not be a great advantage. In a piece at a time method, the tools laying all over the table can get in the way. Having a tool tray to keep them out of the way may be better than putting each one away after each use only to have to walk to the cabinet to retrieve it in a few minutes.
This also gets us back to how the tools are stored. If they are right over the bench with the bench against the wall, a tool tray may be an excess. If like my shop, the tools are stored all over the place, wiping them down and putting them back in their proper place after each use may be more extra work.
Different strokes for different folks.
