Right now, it is impossible to work in Affinity for real as it's missing many pro features. One of them is having my healing brush settings saved so that whenever I enable that tool it's left how I set it up - Brush shape, Current & Below, Align, etc. The solution with Brush window is not practical.
I use very flat healing brush (1% shape) and it's not working in Affinity. Not only that, but also ALT-clicking is not responsive enough for a serious job. There's a tremendous lag, the cross hair is not shrinking accordingly to brush size.
Also, optional tools that are located under J shortcut should require a shift to press in order not to switch on accidentally.
Professional workflows show aim for speed and efficiency, neither of which Affinity Photo is providing in sufficient detail at the moment.
