Coming from older system, what software do you all use?

So I just updated to Samona from High Sierra… what software and hidden features/tips do you all use/have? I’ll go first: Transmission/express vpn - file downloads Simple comic - comic book viewer Fontlab 8 - font design (pricey) VLC - video playback Firefox with ad block - web browsing Flux - filters out blue light at night. Carbon copy cloner. - clone hard drive for backup.

Your turn! What do you guys use?
