Agree lines of code in AEditor is not impressive.

It has taken me very long time to reach this point, where I can edit with my 
own editor. The first experimental versions which I wrote in C++ could show 
the text and was very poor at dealing with edit operations..
It was more an viewer than an editor.

Even though its few lines of code.. its not something that one can write in a 
weekend. Lots of things must be considered and analysed carefully.
1) finding an appropriate undo/redo/macro system took quite some time.
2) figuring out how to support folding took forever.
3) syntaxcoloring+accelerated scrolling requires careful management of 4 
layers of caching. 
4) editing strategies, such as if the cursor should skip tabs or move through 
tabs, supporing different indentsize and tabsize... (took lots of time).
5) made regexp engine that can do multiline selection and skip over foldings 
and search through rectangular selections.. and deal with multiple encodings.

This is just some of the things that has taken _long_ time, even though its 
relative few lines of code.


I don't like your sentence "One of the smallest parts".  I have not insulted 
your IDE..  why Lothar?
