Version history



    • Undo (cmd+z) and Redo (cmd+shift+z) with virtually unlimited history. (Saved locally, no online versioning yet).
    • Select multiple elements by dragging or shift clicking.
    • Move, scale and edit multiple elements, though dragging or the side panel.
    • Use svg and gif images as backgrounds.
    • Nudge elements around with the arrow keys, or push them around a bit further with ctrl+arrow. (uses grid spacing)
    • "outline elements" by checking the setting in the editor panel.

    COLLABORATION - When you are editing a slide and:

    • the slide gets saved elsewhere, the editor updates as well. History (undo/redo) is kept so that you can undo.
    • the slide gets moved, the editor follows.
    • the slide is deleted by someone, you get the option to "restore" (re-add) it.


    • Element snapping lines go to the snapped-to element.
    • Elements no longer jitter when snapping.
    • Each element is now on its own layer. (= Only one element / layer, and no more layers than there are elements. No upper cap.)
    • The text editor should now be more reliable and consistent.
    • Text boxes have height again, but "overflow" if they are not big enough. They grow to fit the content when editing content.
    • The way we save slides has changed to allow for some new features. Even very old slides should be converted correctly, however, there may be some problems with some edge cases. (Though none that we know of at the moment.)
    • The grid is now on top of everything, rather than below.
    • Escape closes popups, de-activates text element, or de-selects selected elements.
    • Shortcuts on mac are now in the format: Cmd+key, while windows uses Ctrl+key.
    • Both Delete and Backspace now remove elements.
    • Ctrl-x for cut.
    • The object transform fields in the right panel have switched places to actually correspond with the "element anchor" and "aspect ratio" icons.
    • Pasted objects are now offset a little (follows grid spacing), if the original object is still in place.
    • Images removed from the imagebank are now also removed from all slides.


    Autoplay is now available for your presentations when needed.

    • You can set autoplay on from the right bottom corner of each presentation by clicking the clock-icon.
    • The default autoplay time is 90 seconds per slide. Change the amount of seconds from the presentation's settings.
  • A big system update

    Today we have published a new user interface, which will push Seidat to the next level. We have fixed great amount of bugs and created numerous new features, that will help you to create, present and share better presentations. Even old presentations will work much smoother.

    The new UI is easy to learn for old users, because the way of use hasn’t changed. The biggest change has been on the dashboard – now everything is much simpler and easier.
