hi @ronaldfuchs2016
There was a reason it was included in previous versions:
The template could not handle the situation when there were too few images on the last row. In those cases, the images were expanded to fill up the space which caused visual issues. The most noticeable issue was when there was a single image and it was made full width resulting in a huge image in the last row. This obviously does not look good and is why we introduced the option to hide the last row. It also makes no sense to hide any images in the gallery, if you want them to be in the gallery in the first place.
The reason we have removed the last row setting in V2:
We have corrected that issue, and have introduced an alignment setting so that the last row can now be aligned. The images in the last row are also no longer expanded out of proportion to the rest of the gallery, so there is no need to hide the last row.
So in summary, please use the alignment setting going forward.
