Improve thumbnail functionality and allow them to be turned off in Pattern Maker Window
While layers, groups, and paths offer you the ability to shut off thumbnails, Pattern Maker does not. As it is a live preview of what you're currently editing, it can slow things down quite drastically, even to select 1 item in the swatch with complex patterns. Often I have to shutoff layer thumbnails since they rerender the thumb for every revision, and would like the same functionality for Pattern Maker. Swatch thumbnails don't seem to be an issue and it would appear they only update once the changes are saved. Since there are many options for bricking, and tiling, it's actually easier to simply zoom out if you're looking to see how your pattern tiles, the thumbnail is often poor reference to identify complex patterns.
That’s correct, the pattern options dialog. I often refer to it as pattern maker partially because the way to get there is “Object> Pattern > Make”.
Really it’s any thumbnail that slows it down for redraw, but especially in the Pattern Options window.
Am I right you are referring to the Swatch preview in the Pattern Options dialog?
As a workaround I generally shut the panel off in these instances which resolves the issue, but it would be helpful to have access to the rest of the features available within the dialog.
