    • Compatible with major file formats including JPG, PNG, PDF, DOCX, and MP4.
    • Inline previews for images.
    • Secure download options for all attachments.
• DataGrid
  • Row and column spanning - Row spanning and column spanning provide greater flexibility in grid layouts. These options allow cells to span across multiple rows or columns, making it easier to present complex data structures and create visually appealing designs.
  • Performance upgrades by module - The core processes have been refined to ensure quicker load times and improved response times.
    • Initial rendering - The rendering process has been optimized to achieve quicker load times and seamless initialization, even with large datasets.
    • Grouping with virtualization - The grouping mechanism in virtualized grids has been fine-tuned to handle extensive data more efficiently, delivering a faster and more responsive experience.
• Diagram
  • Collaborative editing - Enabled multiple users to edit the same diagram in real time while keeping all views synchronized. Each change is instantly reflected and applied across all users, ensuring a consistent state without requiring page refreshes.
  • Force-directed tree layout - This feature utilizes a physics-based algorithm to dynamically arrange nodes for improved visualization. It attracts and repulses connected nodes to reduce overlaps and edge crossings. The result is a clean, intuitive layout that clarifies complex relationships in network analysis.
