1) can be done, albeit with some manipulation using “Sticky vertical mode”;
2) Is already implemented: right click on the vertical ruler at a particular column and choose “sort …”
3) EmEditor is NOT excel. A TSV can be directly loaded to any Excel, no “conversion” necessary!
4) Is also implemented. Again, use “Sticky vertical mode”;
I resent making any application a “catch all” one. Do you want EE to also be a Musical notes editor? I want EE to be lightning fast loaded, lightning fast execution, code editor. I don’t want it even to be a word processor! Please do dot burden it down with too many “features”!
