Done that, they changed priority to low, as soon as they learned that we can still format images with HTML even if the normal system doesn't work.. As I don't want to give HTML permissions to everyone, and the existing workaround to use HTML code for images isn't the best as we can't use lightbox, etc. I think. And even then, some functionality would be lost. So we would have 2 distinct options.
If there would be a way to stay with vBulletin 4, we would stay. But this would be possible only if the image formating options would be replaced. I think it is easy to improve upon original vBulletin functionality if you would be able to add galleries, etc. to articles. If there would be replacement products for vBadanced links directory and vBadvanced Dynamics, it would be easier to stay, and I am sure there could be a market for items like that.
Otherwise there is a strong / compelling reason to move on. As it would be time to replace vBadvanced products there are "no better times" to replace everything. One option would easy: Upgrade to vBulletin 5. That is why upgrading items are important. The other options? Kunena forums, Joomla CMS and a lot of extras.
By the way: If we have some Dragonbyte tech products for vB4 is there a way to upgrade to the vB5 version, or is that like a brand new purchase?
