I would love automatic indenting and automatic indentation fixing.
eg. I would type
for x=1 to 10
and it would automatically insert a tab on the next line.
Or I could highlight a section of code
for x=1 to 10
print x,100+x,100+x
next
and select "fix indentation" and it would change it to
for x=1 to 10
print x,100+x,100+x
next
