@VectorStyler This has nothing to do with the input method. I was deleting characters without typing any input.

@VectorStyler Just a test to see whether it can handle very large documents. Mine had 12K nodes, and the programme became slow and unstable. I discovered subsequently that switching from GPU to Software in the performance preferences helped, and especially turning on the options for, in my case, 24 threads. The biggest improvement then came from rendering layers as image, a setting that did not have an impact when the performance setting was set to GPU.

@Boldline I posted a request for something like this a while back. I looked for alternatives on macOS and found a few. While they aren't dedicated solutions, they offer quite extensive capabilities. The first one is Kando—a free app—and the second is Cirmenu, available on the App Store. There are quite a few apps of this type, but many rely on a subscription model, which isn't really my thing. Check them out; perhaps one of them will meet your expectations.
