I did ask the same question but it boils down to your average joe has never heard of SmartTube. You offer then IPTV for £X a year and say "i can throw youtube premium in as a little bonus" - they've no idea theyre using a free product because they need to log in and it's branded.
I know they could just offer SmartTube without the panel, but like i say more than a couple of people have asked so there's a demand for it.
I know the feeling
people ask for all types of things
especially when it comes to designs , they will instist for instance that the XCIPTV your doing must use a certain background and certain looking icons you tell them its going to be over crowded and due to the background icons will be hard to see etc. i lock them down to exact demands , theme the App. then send screenshots then there is normally a short wait until they come back to you asking can you change the icons ? I am like copy paste the text frreom above you 100% locked these in even though i recomended not to use them.
or can I have a green themed app ? yep wheres your logo ? oh this bright orange and brown one ??????
I have themed apps in the past and thought ............not my cup of tea
take SKY GLASS ????
I personally will not use the theme I just prefer others BUT i make Sky glass themed apps because i know they will sell due to others liking them and of course you can use it as your generic theme , i also use blue and navy themed apps for generic.
If people ask for it then of course make it and sell it .
