[Show/hide layers]

Agreed. The isolate function in Designer is not the same at all and can only be used on a single object, not a group.

A simple Option+Click on the visibility icon like Adobe does it would solve this issue and save so much time clicking, especially with many layers.

["Collapse All" Option in the Layers Panel]

+1

Surprised this isn't fixed yet. Along with the Alt or Option click for layer visibility.

[Epub]

EPUB export from within the application is very handy to have. I use it all the time in Apple Pages.

[Reorganizing Rows in Table]

+1   Dragging rows and columns without tedious copy/paste is a huge time saver for big custom tables, which I build all the time.

[Arrows on strokes (lines)]

Need ability to add arrowheads, pointers, dots at end of lines, brackets, etc. Use this a lot in technical documentation right inside the document.

The graphic is placed, then callouts added, all is grouped and positioned on page.
