I appreciate your fast reply. I am using WIndows 11 Pro Version 24H2 the 2.51 version of Start11. I was making a sugesstion rather than reportng an issue. The software is working fine as I explained in my original post it would be nice the tabs where the title text of the tab itself

The Area marked in red as you can see from the image above very difficult to distinguish a difference between the two Tabs even though one says Multimeda App's The Other is Muitmedia Files however as you see there is still space available for the Tab-Title & Text therein to be expanded. This happens if you have a lot of Groups with 2 or 3 Tabs in them. I use a lot of software so grouping in this manner is much more efficent for me personally. However when glancing at the title it is easy to get confused especially when concentraing on the task in hand.
There is also one other thing that has just come to mind, the group withs at the moment you can select from 6, 8 , 10, 12, 14 & 16. To add a little more cusomization would it also be possible to start from a width of 5, add 7, 11 & 15. Just adds a little more customization. My personal preference would be a width 5, 7, or 11. again this is a suggestion.
Again I would like to say this is a suggestion, that if it is possible I know there are always constraints, could be made in some further update.
I am more than pleased with your excelllent software. Your customer service from my experience is and has always been excellt also.
Kind Regards.
