In todays marketplace, a resizable GUI is expected. sektor packs a lot of stuff into a small space, and due to the garish colours, it's actually very difficult to see, making things like the sequencer pretty useless. On a 70 inch screen, the sequencer feels microscopic. It claims to be a modern synth, yet gives the user no ability to resize even though the developers make a big deal of out of it being customizable. I got a refund.
