Image created with Pencil2D
What I found after working with Pencil2D:
When zooming-out three times the size of the initial canvas, for instance, the Grid boundaries appears on the middle of the canvas. I thought of the possibility of having an on/off button for the Grid. By the way, this boundaries of the Grid does not represent the real Size of the Camera (final render). Not sure if someone has also noticed this but it would be a good idea to have the size of the Grid matching the size of the camera. That will allow the artist to have everything inside it when rendering an image/animation.
When starting Pencil2D it allows me to use right there the keyshortcut LMB+drag for moving all the layers´s content (while the HANDTool icon is selected as a cursor). But right after drawing some lines or just taping at the canvas, this shortcut “LMB+drag” stops working.
I experienced a bad behaviour of the MoveTool. Maybe because I have zoom-out the canvas, not sure. Well, when trying to reduce the image size (which is outside of the boundaries of the Grid) by selecting it first then dragging its corner to a desirable size, it happens that all selected image just disappear. It is Like not able to handle that size. (not always happens this behaviour)
Despite selecting a random Alpha-control value on the ColourWheel-Panel, it always goes to its default value (255) every time another colour is selected. I think that having it “fixed” to a desire value will give a better way of working to the artist. Here another suggestion: To provide to the Alpha-Channel box-value, a slide-control for a fast changing value (like the Pen-Tool slide´s size)
When using the toggled-color-palette (shortcut “C”), in RGB or HSV mode, changing any value on the saturation/hue/value/alpha´s slides, or Red/Green/Blue/Alpha´s slides, will make the shortcut to stop working till you tap on the canvas or in the close/toggle© button.
The PEN-Tool has no Feather feature available. I mean it is greyed out with a value that was lately set-up by the last Feather-BRUSH-Tool value used. If I want a Feather value of zero for instance, while using the Pen-Tool, I have to go to the Brush-tool to change its Feather to zero, and return to the Pen-tool in order to be applied to it.
I will report these ideas.
