Don't show the main view during activation if it's not necessary

[YourOrdinaryCat]

If I open a font on a new window, and later open the app through the start menu (without having minimized, closed, or opened any windows prior), I expect to see the font I opened on the new window, not the full list of fonts. I understand opening the main font list back up when the main view is consolidated, but I don't think it should be shown every single time. In general, I think the main font list should only be shown if it was the last view the user switched to, or got closed.

I want to know if the behavior described above is something the devs would want before making a PR for it - it's all achievable through ActivationViewSwitcher, which I describe on my blog if devs are interested (the overall machinery for this scenario is not very well documented, and I haven't found many usage examples): https://yourordinarycat.github.io/dreamscape/2023/12/23/ActivationViewSwitcher.html

Edit: I just realized, it's definitely a weird time to be posting this 😅 happy holidays!
