You've inspired me.
Like you, I charge with a timer, and I use two other items: a multimeter and a watt meter. I use the multimeter to check battery voltage before and after charging. The watt meter shows how many watt-hours I've put into the battery, and if the green light comes on the charger and the watt meter still shows more than the usual green-light watts, I know to leave it charging because it's equalizing.
That adds up to a lot of items to collect for charging, and I have to find a place to put them where they won't be knocked to the floor. A stand like yours would be a big improvement.
