Thanks for your feedback
1. Try to adjust the ratio in QD settings - Grid
For Capture in new tab, at now, you need to size your window manually
2. Some website can't be captured with the integrated update method...
For this you can capture it in new tab but 10000s is very strange, 2000s is the default value
Don't mess that you can open issue on https://github.com/MatMoul/quickdial-webext/issues
