I think Themler is a great product. Unfortunately themler has a major drawback this is, if your client wants to do a simple colour change of say the menu, my clients can't do that unless they buy a subscription.
I think if you buy the E commerce or pro THEMLER EDITIONS there should be an admin portal or someway that my clients can change the site I design for them or maybe possibly allow web designers to buy a licence for their clients at a heavily discounted price. For me having to pay for this would not be fair but I could learn to live with this but only if it was something like $20 or less. This site https://themify.me/ enables my clients to change there design and unfortunately unless themler changes this major design flaw, I can't use there software. Unless I ask the client do you need to change your design after I hand it over to you and they say no, then I can use the software, but I don't think many clients will say no to this because I wouldn't.
If you agree with what I said above please vote. Only together can we make a difference and make Themler change their software.
