This drops fomantic-ui as css toolkit and introduces tailwindcss. With
tailwind there are no predefined components, but it's very easy to
create those. So customizing the look&feel is much simpler, most of
the time no additional css is needed.
This requires a complete rewrite of the markup + styles. Luckily all
logic can be kept as is. The now old ui is not removed, it is still
available by using a request header `Docspell-Ui` with a value of `1`
for the old ui and `2` for the new ui.
Another addition is "dev mode", where docspell serves assets with a
no-cache header, to disable browser caching. This makes developing a
lot easier.
Mails are filtered once by using an imap search and then by some globs
to filter files and subjects. Imap can search by subject via a
string-contains, but not via globs or patterns (afaik). The subject
filter is applied to all downloaded mail headers. Now for post
processing (moving to some target folder or deleting), it can be
chosen to post-process all "seen" mails or only those that matched all
filters.
Show also "empty tags", where the count is 0. Before only tags with a
count > 0 were displayed. When searching this is fine, but when using
drag&drop to attach tags to items, it is good to see all. They can be
hidden via a button.
The tags are now ordered by their count descending, but regarding to
the overall count – not the current view. Otherwise the tags are
reordered when clicking on them, which is confusing. Also it then
shows the "more important" (most used) tags first, even when the
result is a subset.
A fix was made related to updating the menu. When coming back from
the detail view where a tag with prior count=0 was associated, the
menu didn't show it, because it relied on a previous state, where this
tag were not included.
For some to me unknown reason, changing the dom slightly (removing
hidden elements), resulted in a different event dispatching. The cards
while being attached to an event would reload the page as if the event
is propagated. This happned by commit #8d7b3c7d in Home/View.elm.
Adding the hidden nodes back into the dom, "fixed" it.
This change now gives a better fix in assuring that every anchor has
either a sensible `href` or an event and a `href #`.
The functionality of the search bar is now in the search menu, too.
The search menu shows one input field for "textual search", which is
either the fulltext search (if enabled) or a basic search in various
names.
