Live Draw - Download 
Live Draw an aseprite extension that allows you to draw on the canvas while animation playback is running.
Saw this open issue on github Draw on animation playback #1320 and its been few years and this feature is still not yet available.
My laziness, forced me to create this extension just to make this fire in under 5 minutes.
Finally i was able to finish this project, also added few features for better controls
Key Features of Live Draw
Brush Options for Drawing Dynamics:
- Brush Modes: Choose the behavior that fits your drawing style.
- Static – Fixed brush size (default).

- Ping-Pong – Brush size alternates between growing and shrinking.

Optional : Loop Grow/Shrink checkbox for Shrink and Grow, allows looping of size changes.
Note : While Live Draw supports custom brushes, Brush Modes (Grow, Shrink, etc) and Angle Modes (Rotate, Random) do not yet apply to custom brushes. This functionality is planned for the future update!

How to Use Live Draw
- Create a New File and add a few blank frames.
- Open Live Draw – Navigate to Edit > Live Draw in the top menu.
- Click “Play Animation” button to play animation.
- Click “Start Drawing” button to activate drawing on the canvas.
- Unleash Your Creativity – Hover over the canvas and start drawing while the animation playback is running (No mouse clicking ).
Note: Live Draw is compatible only with Aseprite version 1.3 and above.
Canvas Drawing Control: Due to an Aseprite limitation, mouse left-click can’t be used to draw while playback is running. Instead, use the dedicated Start Drawing button, which can be conveniently activated with a customizable hotkey (Edit > Keyboard Shortcuts).
