Search++ is a work in progress. It is not feature-complete and has not undergone thorough testing yet. Use with caution. That said, your feedback is welcome and very much appreciated. There is a discussion topic in the Notepad++ community, or you can create a GitHub issue.

• Fix failure to reset match counter after a Replace All.
• Add missing logic to make Replace Before and Replace After work properly after stepwise Find or Replace.
• Remember the contents of the Find and Replace boxes between Notepad++ sessions. Synchronize Find and Replace box contents and all settings accurately when switching between the docking dialog and the non-docking dialog.
• Add to the help file to clarify the special cases for Replace Before/After and what does and doesn’t reset the match counter. Correct broken links to this project on GitHub in the help file.
• Fix some mistakes in the GitHub project setup: some ICU4C files that were needed were not included, and some that were not needed were included.

There is a help file.

To install Search++ download Search++-0.2-x86.zip or Search++-0.2-x64.zip, depending on whether you're using 32-bit or 64-bit Notepad++. Unzip the file to a folder named Search++ (the name must be exactly that, or Notepad++ will not load the plugin) and copy that folder into the plugins directory where Notepad++ is installed (usually C:\Program Files (x86)\Notepad++\plugins for 32-bit versions or C:\Program Files\Notepad++\plugins for 64-bit versions).
