The current goal is to support as many platforms as possible, and make FileBot work well on all of them. Other than that, there's a never-ending stream of bug reports and feature requests here in the forums.

There is no grand roadmap for the future, as FileBot is
(after 10 years of development) a rather mature product and works perfectly well for the vast majority of users
(though keeping it that way is a task in and of itself).

Indeed, FileBot was an excellent piece of software back when it was free. But you can't hold that against me. You're not paying for the delta since last year. You're paying of FileBot as a complete product that does what it says. Think of it as return on investment
(from the developer perspective).
Here's some interesting thoughts:

The main point to take away from this, is
aligning the interests of users and developers. The subscription model allows user to get FileBot for cheap
(on the short term) which is good for users, and ensures strong incentive to keep my current users happy
(instead of focusing on new users) which is also good for users.

Personally, I dislike subscriptions as well, and this is why the 1 year license is not a subscription, but a simple one-time purchase. So you can
(and have to) reevaluate if FileBot is worth $6 to you or not once a year.

A life-time license / one-time purchase option is available, but it's significantly more expensive, so you can choose between a reasonably-priced subscription or an expensive one-time purchase. The choice is yours.

Plex is great. What I dislike is that none of the developer are active in their forums, so you can never actually talk to anybody who's actually working on the thing. It's probably company policy, same as with all the other tech companies
(Google, Microsoft, Apple, Samsung, Synology, QNAP, etc). That's because developers are expensive and as a company you don't want them to spend their time on non-engineering tasks, such as talking to users.

FileBot is a one-man show, so I make company policy, and evidently, I'm still here talking to you, and hopefully have been able to earn your continued long-term business with this rather verbose reply.
