‘oneware’ or OneWare Studio is the successor to VHDPlus IDE, which already got classic confinement as ‘vhdplus’.
Like VHDPlus, OneWare Studio is an IDE which needs access to the users file system. It is an .NET 8 self contained app. The Reason we chose to publish it under a new name is that it is a rewrite with new features that are incompatible with VHDPlus and needed a new name for it.
More information about the software can be found at https://one-ware.com/studio
I case it helps, here is the classic confinement request for the predecessor VHDPlus: https://forum.snapcraft.io/t/request-for-classic-confinement-vhdplus/24898
For OneWare, the requirements are the same
bump
Our software is released for Windows and MacOS already, just waiting for someone to review this.
If there is anything I can do to speed up the process, please let me know 
hi @HendrikMennen, apologies for the delay.
Similarly to the VHDPlus forum topic you linked, this snap is itself an IDE so it meets both the requirements for classic confinement and fits within one of the existing categories for classic confinement to be granted as per Process for reviewing classic confinement snaps .
Has the latest revision been submitted to the store? Once confirmed, I will begin publisher vetting.
