Related Issues / Discussions

Few occasions where users on Discord were asking if it is possible to switch back to paged gallery view.

QA Instructions

• Have or generate board of images that require more than one page of space (ideally 50+).
• Verify that "Use Paged Gallery View" checkbox activates paged gallery layout.
• Switching checkbox off returns back to infinite scrolling.
• Arrows switch to adjacent to current page.
• "Jump" button allows numeric input and actually jumps to required page either by clicking "Go" or hitting Enter. Esc closes "Jump" popover.
• Resizing image thumbnails and gallery window change amount of pages accordingly.

Merge Plan

uiSlice.ts + uiTypes.ts bump state version; if main has new UI state migrations, merging the versioning logic might be needed.
Other than that, PR should not introduce any problem when merging.
