* Refactored control panel “Plugins” tab to make the elements more
reusable
* Refactored the display of plugin tiddlers to use the same format as
the control panel (as suggested, I think by @danielo515), adding the
shadow tiddler listing as an overridable extension tab
* Added a new tab in the “More” sidebar providing quick access to all
installed plugins
This commit permits language plugins to carry the field
“text-direction” with the value “rtl” to trigger right-to-left layout
of the entire page. We also adjust the sidebar layout to work in RTL
mode.
There are still a number of problems to be addressed:
* Brackets and other punctuation incorrectly placed within en-GB UI text
* System tiddler titles are rendered semi-back-to-front (eg
`languages/ca-ES/:$`)
Starting to address #1845 and the discussion in #2523.
* Fix word wrapping in code blocks
When you create a code block with the three back ticks any thing that
was wider then the pre block would be word wrapped. That causes code
snippets to look odd.
* Make code wrapping a theme tweek option
The dropdown can be summoned by clicking on the search field. It will
only appear if the search field is not empty. When the search field is
not empty the dropdown can be also be summoned by clicking on the arrow
or search result count.
There are still some wrinkles where the dropdown doesn’t appear when
expected; I’d appreciate feedback to help reproduce those cases.
This change should still work with custom search result tabs.
Now the sidebar is a fixed overlay. It is scrollable, taking up 50% of
the height of the screen, so that the underlying page can be partially
seen.
There’s more to be done: on narrow screens we probably want the sidebar
to be hidden by default.
There’s not much to making the toolbar button styles switchable: the
change to the PageTemplate introduces a new configuration tiddler that
controls the button styling. Most of this commit is the user interface
for changing that setting, including the translatable text. I think
this again demonstrates that we need to be very selective about which
configuration options have a UI included in the core. Otherwise, a few
dozen more of these settings will start to become a significant
fraction of the core.
