I have discovered what I believe is a bug in the hint displayed over the add-field button in tiddler edit template. Steps to reproduce:
Edit any tiddler or create a new one.
Add any text in the “field name” field (so that adding the field becomes possible).
Hover mouse over the “add” button.
A hint saying {{$:/language/EditTemplate/Fields/Add/Button/Hint}} is displayed:
I tested it on tiddlywiki.com and on an empty TW. It is the same in current v5.3.1 and in the v5.3.2 prerelease. I have looked through the archival releases: the first one with this bug is v5.1.22, it doesn’t happen (no hint is displayed at all) in v5.1.21.
I’m not familiar with the workings of the language mechanism, so I can’t propose any way to fix this.
Meta question on the side: is this the right place to initially report such things? Or is it better to make a GitHub issue straight away?
Bug reports are very valuable to the core team. Minor issues like this are all too easy to ignore, and so we really appreciate the trouble that people take to report them. You’ve already performed the most critical task by identifying a way to replicate it tiddlywiki.com.
As @pmario says, a GitHub ticket is necessary in the end, and so is always appreciated. But we want to make it as easy as possible for anyone to report a bug, so we’re happy to receive reports in any form.
