Ever tried "Jedit"
can it do the things that separate the men from the boys?
Column edit (cut, paste, change)
Indent a block (blanks or tabs) in in one keystroke
Find the match to '{', '(' and '['
uppercase or lowercase blocks
compare two files
find in file or directory or directory and subdirectories by file name(s) or file extension(s).
complex edit such as replacing /n/nwhateverpqrsomething/n replaced by /nwhateversomething/n where 'whatever' and 'something' are unspecified data.

If indeed it can I may have a look
