About the other 3 (minor) updates.
They are just on the cosmetic side, something I wanted to rectify for a long time.
The space between the chcekbox/radio button and the text label in the Options page.
Minor but its been bugging me for quite some time.
For SimpleUndoClose theres also a little more space between the page icon and text.
Spacing adjustments also in the SimpleExtManager update.
