I am an author of EmEditor. I just came across to the Best Text Editor site, and the EmEditor review, but unfortunately EmEditor was not correctly reviewed, and I was very disappointed by that.
EmEditor does support Column Mode. It is called Block selection by EmEditor. You can select block text by using mouse while pressing ALT or start using CTRL + SHIFT + F8.
Code Folding is now supported by EmEditor Professional v6. It is called Outline by EmEditor.
User Tools: You can capture Standard Output of user defined external tools.
I believe EmEditor is a best text editor. It completely supports Unicode, and it is a very fast text editor. It has a powerful tab features. It is very stable. It is extendable by using plug-ins. It supports powerful macros, and supports many more features!
If you have not tried recent versions of EmEditor, you should try EmEditor Professional , and you can download from the EmEditor web site http://www.emeditor.com/. It is a top rated developer software and text editor by CNet download.com.
Please also change the title of the software to EmEditor Professional from just EmEditor.
