installed the latest tabifier for 998.
1. When I open the plugin dialog, left pane is not visible. When I resize the window, the left pane is visible.
2. The code on the right side does not scroll and it's hard to find the effects of your changes
3. I do not see any OK/Cancel/Apply buttons. So when I make some changes and close the dialog, all my change are lost.
4. Most importantly, when I open the tabifier dialog, the CPU usage goes to 100%. When I close the dialog, the usage goes back to 0-1%.
