I think i first got this 3 years ago (at least 2 years for sure). I needed it for chat widget with some customisation options and option to connect it to things like Whatsapp, Messenger, ...
I upgraded it recently, because it has been solid and there is also a lot of new stuff added. I didn't immediately needed an upgrade, but didn't want to miss the deal and i think more sites could need a quick chat option. A lot of things i still need to explore, but it is clear that it deserves attention. Also want to mention that i had a quick response for my question per mail.

Many features are a bit hidden here on Appsumo casually under 'show all included features', but i think it is good to mention most of them again, like ticket organisation, Whatsapp campaigns, Chat flows, Contacts, Mail form option, AI assistance and connection to several services (like Straico which is/was also on Appsumo), Tasks, Logs and more. You can build a fully custom widget (add several elements) and such. There are apps (iOS / Android from Anychat) or connect Tawk.to app and such. Integrations for Wordpress and so on.

Room for improvement? Maybe some improvement for contrast for the dashboard dark mode colors. The gray (rgb(97, 97, 97)) is a bit dark.

There is probably more possible. Trying things out like getting the URL of the page when someone opens chat (which is maybe possible with some JS code snippet) to use this in chatflow so for example if someone needs more info on a product (visiting product page or something) text will be send to agent or as chat message. Anyways.. 5 taco's.
