My two cents on what D needs to be more successful...

[Ecstatic Coder via Digitalmars-d]

Coedit is actually by far my favorite IDE for D testing and 
debugging.

I liked it immediately after I saw that it doesn't need to create 
a project if all you need it compile and test a small D script.

I know I can create a project, but for tiny projects I don't use 
it on purpose, despite I personally prefer to have only one file 
per class, because projects tie the source code compilation to a 
particular IDE.

All my tools can be compiled with "dmd xxx.d", which is really as 
simple as it can possibly be.

I know that "dmd aaa.d bbb.d ccc.ddd ..." works too, but as long 
as my scripts are just a few hundreds of lines of code long, I'm 
ok with that.

My only concerns with Coedit are a few usability problems when 
editing the code.

By default :

* When I copy a block of code, I have to select it from the end 
of the previous line, or else the inserted code indentation goes 
wrong.

* When doing a find and replace, Coedit replaces the next 
occurrence despite I don't see it and I'm not sure I want to 
replace it, instead of the one highlighted under the cursor, 
which I'm totally sure I want to replace.

* A closing brace is automatically inserted at the wrong position 
and with a unwanted blank line if I put enter to insert a missing 
closing brace.

   I'm not sure, but I think the case is the following :
   {
       {
           {
           }<- editor bugs if I put enter to manually add the 
missing brace on the next line
   }

* The regular expressions are always enabled by default when 
searching text.

* When I change some preferences, Coedit only keeps them until 
the next restart.

I know that's really not much, but this bothers me enough so that 
I still prefer Geany for pure coding sessions.

Only after I've finished programming the core code and prettified 
it, I switch to Coedit to try compiling, testing and debugging it.

Except for these tiny annoyances when typing code, Coedit is an 
exceptionally good IDE, and I really like it a lot, that's why 
it's the only one I've mentioned.

I don't mind posting my usability remarks on your Github account 
if you confirm me that they can indeed be considered as "bugs"...
