Thanks for taking the time to write this report.

The extra space is a feature that you can switch on and off 
(-Trimming in the .candy file). It is "on" as standard to avoid possible
with layout sensitiveness of Haskell and candy.
The unicode signs for =<< and >>= can be set in the .candy file. We should
find a reasonable default.

You are right. Find and replace is missing not only in this respect. We will
add this to the wish list.

This should be possible by selecting the "package" scope in the modules or
search pane.

Go to Preferences/GUI Options and select "Complete only on hotkey"

This will be much enhanced in the next version. The highligt part was 
completely rewritten when adding the debugger.

Sorry, but this is currently not on our list. But if someone implements it,
we will be very happy. 
Thanks again and good night
