The devs definitely want to improve it, but unfortunately, it’s unlikely to happen any time soon due to technical limitations 
The short version is that it’s pretty expensive to have semi-transparent glass (especially with how often glass is used). And to do that, it would require an engine overhaul to be able to correctly render it.
Similarly, making the glass 100% transparent looks very weird (aka it’s invisible, except for borders)
