Thank you for the detailed information @Francois_Douville
Because there is a lot of overlap between Tiles and Slick and things can get confusing, I made two separate topics for them.
In this topic the focus is Tiles, but I’ll happily answer your questions about both here now.
This is intentional and is mentioned in the OP. The editor preview updates with every letter you type into the composer. Having the script to create either Slick or Tiles fire like that to keep the preview accurate is too much overhead.
My goal is to follow the model that Oneboxes have where they update only if they are modified. However, this remains a future improvement and not currently implemented.
The static preview looks like this:
The more I look at this, the more glaring the problem here appears to be.
Previously, Tiles would wait for all images to load before creating the grid. So the 10 seconds you referred to is Tiles waiting for the images to load. Internet speed aside, you’re right. +10 seconds of staring at nothing is no good.
So, I updated Tiles to address this. From now on, Tiles won’t wait for all images to load. It will orginize the grid every time a new image is done loading. There’s still room for improvements here and I’m open to suggestions but the wait time should be drastically reduced now since you, at least, have something to look at while things load.
This should not be happening. Please update the theme and let me know it the issue persists.
