BBEdit still has the best multi-file search-and-replace feature of any editor I've ever used. Tons of options, a visual pattern builder, multiple simultaneous search source directories and the option to save search sets, it's saved me innumerable hours of tedium.
I still keep updating it (been using it since 1.x days) for multi-file search as well, even as the rest of my workflow is tmux, nvim and other command-line tools. BBedit's diff tool is excellent too.
I've previously been able to edit large files with vim, emacs as far back as 1998 and other editors on OSX for a while, what would happen in editors such as hexfiend, glogg, pilotedit,vim,emacs etc ?
Unless bbedit available for another platform that wasn't osx ? (my history is shady).
The multi file search and replace is so good that it kept me coding Python in BBEdit long after I should have switched to something better suited to the task.
In regards to keeping the art on-chain, the immutability is a real problem. What happens when someone stuffs illegal data/images on the blockchain? Once a bad actor sneaks trade secrets, doxxing material, or CP onto the chain, it's there forever. By design, deleting data from the blockchain isn't possible.
It's worth the price for that one feature alone.
