Time to defend Tiwag here, for once.
The original "bug" was something that I perceived as a very useful feature. Although one could object it should be an option because some people may not like it. Personally, I found it very useful, but I am fine with pressing Ctrl-F again, too.
When you scroll down and click somewhere and then hit F3 the search starts at the beginning of the page again and NOT where the caret is.
Not true. If set the caret further down in the document, it certainly starts at that position.
The other is when you open another window and hover mouse over codeblocks, then codeblocks is moved to the front and my just opened window is defocused.
Not true, either. This is a X feature / optional Windows setting. It has nothing to do with Code::Blocks.
