Yeah, really tough to tell, one would really need a collected list to look at the alternatives. But there were quite a few core changes introduced this year that make a big difference. Looking on tw .com I note versions 5.1.22/23+5.2.0/1 were released during 2021. Two recent changes, of a more “ah, finally!” nature is the possibility to now editwidget a field in the current tiddler, and to freely name fields.
But I’m sure what is most valuable are things I don’t understand, under the hood. The “Cascade mechanism” is probably way more valuable than I can tell. And the improvements to the ListWidget… given how ubiquitous that widget is, then any improvement should have a big impact.
And just so many new and useful filter ops, including the filter prefixes ( :...
)!
But one unofficial plugin that does stand out to me is Flibbles Relink plugin… (if that indeed was in 2021?)? Very useful (and should probably be in standard distro).
I note many other great creations but I just don’t use them so I’m not qualified to vote on them.
In all, I leave 2021 with a sense of humbleness. Wow… you guys!
