Add a features

It is nice to add some features to your plugin a way that ensures the completeness of the plugin 1- display or hide the sidebar 2- Preview attachments without screen transitions. The following attachments can be previewed. Image, Audio, Video, PD 3- Make the selection box searchable 4- Enhance the issue list view to keep list headers fixed with CSS ( position: sticky ), seamless updates using AJAX to avoid page reloads 5- a compact criteria box for improved usability
