* Experimental. * Getting somewhere. * Good zooming behaviour. * Working timeline zooming & panning. * Clickable timestamps. * Dragging cursor * Timeline panning buttons. * Capping at current time. * Scale limits. * Better ticks. * Time tags fading in smoothly. * Removed seconds. * Better tick spacing. * Vertical panning as zooming. * Organizing the code.. * Replaced d3-zoom with native events. * Got rid of scaleX * More code beautified. * Almost done polishing the code. * Some cleanup. * Better request triggers. * More cleaning up. * Styled the timestamp input. * Final cleanup. * Update yarn.lock * Zoom tracking. * Animate timeline translations. * Fixed the PAUSE button glitch and updating the time control info. * Opacity fix and timeline arrows removed. * Fixed the red vertical bar. * Use preventDefault() on timeline scrolling.
