A few things I wish Visme offered are an on-click animation feature, the ability to upload mp4 videos into presentations without buying the enterprise plan, and the ability to manage animations more precisely (example: to simultaneously shift the entrance/exit times of objects that have different entrance/exit times). It can be very tedious to go through and edit every object's animation time if you need to add something to the beginning of a slide. It would also be great if you could make an audio file extend over multiple slides without making it the background music for the whole presentation.
I'm being nitpicky on this one, but my presentations rely on synchronizing visuals with audio, so it would great if there were software that could help to facilitate that instead of having to time out animations manually. Finally, I would love it if you could couple animations with sound effects.
Oh! And that reminds me. It'd be great if Visme had a sound effect library too! Review collected by and hosted on G2.com.
