- Changed BrowserScrollOffset and ListView.ScrollOffset from int (row index) to ui.Dp (pixel offset) for smooth per-pixel scrolling - Updated HandleBrowserScroll to use raw Dp delta instead of row-based scrolling with minimum ±1 row jumps - Fixed search not triggering new frames by detecting query changes in main.go FrameEvent handler - Fixed click misalignment by indexing RowFilenames with local index i instead of rowGlobalIndex - Fixed bottom clamping using actual BrowserListHeight and corrected formula: maxScroll = totalRows * rowHeight - BrowserListHeight
