    • Hello community, I’d like to share an improved version of the L2smr editor for StaticMeshes, focused on solving some workflow issues I found in the original tool. CreditsThis project is based on the original acmi/L2smr repository https://github.com/acmi/L2smr , created by acmi, and I updated it to Java 17 with some additional features. Issues in the original L2smr Too many windows: each StaticMesh opened in a new one → cluttered desktop. No search: navigating through hundreds of StaticMeshActors was slow and tedious. Added improvements Flexible views Single Window Mode: reuse one window instead of opening new ones. Multiple Window Mode: still available for those who prefer having several views open simultaneously. Real-time Search Field Instant filtering as you type. Case-insensitive search. “Reset” button to quickly clear the search.     Installation and Execution: Clone the repository: git clone https://github.com/Jeep12/l2smr.git cd l2smr        2.Build the project:   ./gradlew build        3. Run the application:     ./run.bat      Or simply double-click on run.bat.     The run.bat script automatically extracts JavaFX from the included javafx-17.0.2.zip file in the javafx/ directory, sets up the required libraries, and launches the application. You don’t    need to install JavaFX separately.      Repository: https://github.com/Jeep12/l2smr     Maybe these features already existed in another version or fork, and they might not be very big changes, but since I didn’t know about them and found them necessary, I decided to          implement them myself and wanted to share them.
