Hi Zlatko,
Like Roland said, PSPad is a freeware editor, their logo say's it also and the description on their main page start with "PSPad is a freeware".
Sorry that, from your perspective, you find it bloated.
Even if I will remain loyal to UltraEdit, from my perspective, PSPad is full of features and options.
About adding keywords. Yes, adding more functions, messages, and notifications is in fact pretty easy,
I guess lots of guys among us can add many more thousands.
This limited plus or minus 5,000 list is made of the more commonly used, to avoid ending with a too big database that might affect the the editor performance.
When I use an interesting API that is not in the list, I simply add it, one at the time.
This way I keep the database unbloated.
I agree, it's a nice editor. I'm an UltraEdit user but use others when forced to. (like on RPi) Too bad it's Windows only and not open source.
