* fix for "Open" tab placeholders in FireFox
this PR fixes the placeholders in FireFox not being removed on drag-leave from time to time
it consists of 2 mods where apparently both are needed:
- creating a `droppable-item` macro where whitespace is trimmed. that macro contains the droppable and inserts the placeholders
- removing the ` ` entity in favor of an inline style `height:2em;` on the placeholder div, putting it in a macro where whitespace can be trimmed, too
I'm investigating if there's a similar fix for the top page dropzone
* remove unnecessary whitespace trim, add css classes
`.tc-sidebar-tab-open-item { position: relative; }`
`.tc-sidebar-tab-open .tc-droppable-placeholer { line-height:2em; height:2em; } `
* replace times entity with close-button
* add sidebar-open-tab styles
It seems that there is a broader problem with the way that the button
is embedded within the label of a checkbox; even on Chrome it meant
that the checkbox active state was triggered when clicking on any of
the buttons. The user experience was in any case confusing; it wasn’t
obvious that clicking on the label to the right of the button would
flick the checkbox.
The solution takes the buttons and labels out of the checkbox label.
In practice, if you look at TabsMacro you’ll see that the width of the
tab content is wrong, and will usually overflow the container. Next
step is to fix that by using flexbox…
By rearranging the `[all[]]` operator we are able to ensure that shadow
tiddlers get processed before ordinary tiddlers. This makes it easier
to create custom stylesheets that override the core.
We get a significant speed improvement of >10% by rearranging filter
operators to bring to the front the operators likely to reduce the size
working list.
Fixes#82.
The old behaviour was to parse the content of a widget or html element
in block mode if the opening tag was followed by a line break. The new
behaviour requires two line breaks.
This makes it possible to include linebreaks more liberally within
wikitext, although care must still be taken to only use double line
breaks when the block mode behaviour is desired.
The code change here is very simple, just a single line change in
html.js. Most of the other changes are to convert various single line
breaks into double line breaks.
Still quite a few details to work out, but this shows the basic idea of
re-using the theme mechanism to handle language plugins.
Comments and questions welcome.
