Adding features such as tabs in the long description would bring a more contemporary look to the product pages, which ultimately brings about a better user experience to the storefront. Competitors have it, and freshening up skins on a regular basis is something we need to do to remain competitive in the marketplace. See: https://effects.pressero.com/page/tab-effects for some tab effects that can be added by ProServices.
There are many tab designs that can be added by ProServices. For those interested, here is a link to some options:
I do agree with Jim Riddles' comment: It is relatively painless to do yourself if you know how to code it. I received a request in ProServices for this, therefore I added it to this portal so our developers can have a record of the request and decide whether or not to add it as a standard product feature.
Just my thoughts on this idea. The long description supports modifying the raw HTML. I would prefer to use my own HTML code to create tabs rather than rely on the pre-supplied tabs provided by Aleyant. Although I realize that not all subscribers have the knowledge in-house to achieve this, it should be relatively painless to achieve the results you are looking for with the current setup.
