I am actually trying to find a slide out plugin that shows on left or right, click on it and it slides out, where I can add widgets. I have found a couple, sadly none of them are compatible with latest WP versions. So I thought slide in might be it, however by default slide in only gives you three options
Show message after this much of my page has been viewed: %
Show message after scrolling past element with this ID: #
Show message after this many seconds:
Is it possible to achieve what I am trying to do? Also is there an easier way or another plugin thats compatible with latest WP.
