I think some glyphs are quirky and fun and others look plain and staid. If this were my project, I'd scrap the lowercase. The lowercase doesn't make a lick of sense. I like BDGKNRSTUZ. If you make the other letters match that style, you'll end up with an amusing version of a Federal Reserve Bank Note type of idea. The flip thing you're doing with the O isn't working. Q's tail doesn't have the same personality as the mustache stroke on the R. You need to spend more time on the 8...look at some examples of the style you're modeling this on for ideas.
I don't think there's anything inherently bad about either platform; it's just not for everyone. I remember in 1985 when I tried a Mac...I just didn't connect with it and took the Amiga path to Windows. I don't want to derail this thread with a Mac/PC fight but it's frustrating to see all the good font tools coming out on the Mac while I'm struggling with Fontlab in Windows.
I've recommended it Fontcreator to clients who need to make some small changes to a font. I think, of all the low-cost Windows font tools, it has the quickest learning curve. Typetool is around the same price but is almost as unapproachable as FontLab so why bother? As for me I only use Windows tools because I can't work on an Apple computer. Every ten years or so, I buy an Apple computer. I try to use it for a month and I just go completely out of my mind with frustration and go back to Windows. It's not for everyone. Said computer gathers dust for a decade when I sell it for $50. It's a pattern and I'm due for a new one in 2018.
Yeah, I'm missing out of some wonderful font tools but I just can't deal with that file system. It's like Passage to India; not everyone can make the transition.
Now that FontCreator supports both curve types, the only critical component that's might be missing is interpolation. Is that correct? I don't think it's capable of axial interpolation. An aspiring type designer will eventually get to a point where they want to get some interpolating done. At minimum, a single axis interpolation for weights.
Maybe that's where plugins and external tools could fill the gap. Are there any standalone Windows tools for this? I know about DTL BlendMaster but I don't know if you'd need another tool to get it into IK format first.
