1 - Erase on-the-fly via shortcut to some Paint Tools
The ability to have the eraser dynamics of Paintbrush, Pencil, Airbrush, and Ink tools. For example, using a key to change the state (erase or paint with the current tool), for instance, the Ctrl+Shift or another choice. So we would have the same brush to paint and to erase ... I find it interesting and important to have the option of deleting the same spot that we are using to paint or draw and the fast way (for example, as color picker via Ctrl key)
We have the possibility to share the brush/dynamics with the eraser too with Preferences > Tool options = Paint Options Shared Between Tools. It is good if the use between the tools is not repetitive or massive. In MyPaint and Krita, we can use the key 'E', to enable temporary the eraser ability. Basically we talking the same behavior that actually we have with pick color on all paint tools, via the Ctrl key.
I've made a short video using Krita... to exemplify this feature... in this video is used the key E to enable the feature to erase and again E to disable the feature. On MyPaint the feature has the same behavior and shortcut key.
Link to short movie: https://youtu.be/36zctEmkPlMI really like this feature from Krita and My paint but I think it would be very inconsistent with from the way every other short cut we have. does switching back and forth between tools using N, P, E, A, and K work for you?
I personally turn off the sharing options in the tool options because when I use the brush and the pen or the air brush I expect them to be different. I manly use brush and the eraser but I think I might turn them back on now.
2 - Dynamic brush size
One way to enlarge and / or reduce the brush without having to be constantly using the tool options or the [and] for this. This can be done on Krita, using the SHIFT + Drag.
Link to short movie: https://youtu.be/wOGBDRWpgOsIn part, the graphic tablets, do it... but is impossible to resolve the scale range. To have the possibility helps the artist to have on-the-fly different range scales is better.In 2014 I had a short thread with Alexia and the focus around the Size was the possibility to have a range (min and max) in the UI. This is another thing interesting... but this signify also to have the presets and not necessarily this resolve all artists' tasks.To have a feature to scale dynamically the Size is interesting to avoid, for example, sets of brushes thought to different size ranges; a fast way to control range sizes with graphical tablets, etc...Here is a plug in that does what you are looking for. I agree that this would be a nice feature to have come with GIMP. There have been a few brainstorm pages over the years about this topics here, here, here, here, and here. I don't know if there is a feature request in bugzilla though.The plugin does not work in GIMP 2.9 as the function it uses is deprecated. I am unable to log into the plugin registry or I would report the bug I am having. Here is the error I am getting.WARNING: Plug-In "dynamic_brush_resize.py"(/home/andrew/.config/GIMP/2.9/plug-ins/dynamic_brush_resize.py)called deprecated procedure 'gimp-brushes-get-spacing'.It should call 'gimp-brush-get-spacing' instead!
3 - Dynamic zoom
A dynamic zoom directly with the mouse or tablet's stylus ... the keyboard shortcut (+) and (-) are difficult to use in painting session. Zoom tool becomes a bit annoying while painting ... every time you have to select via tool box or via keyboard zoom then painting, and to reselect again the paint tool.
On MyPaint and Krita this feature is present, and they are similar behavior. On MyPaint, for instance, the zoom is enabled with Ctrl+Drag.This is honestly one of the greatest features of My paint. To very quickly zoom in and out like this is so amazing. I would add shift+Drag to rotate the image once that feature is done as well.
