I suggest adding the function of combination arrangement,as shown in illustratio.
This screenshot has no errors,I hope EmEditor can achieve the effect as shown in the picture.
for example:
Apple A
Watermelon B
Pear C
to
Apple A
Apple B
Apple C
Watermelon A
Watermelon B
Watermelon C
Pear A
Pear B
Pear C
