  * DnD drop targets need work, as they aren't being handled yet. This will be easier with plugins to test it.
  * The cell renderer uses cairo drawing. Instead we should use icons for the Git states so we get GDK 
texture caching.
 
-## IdeRunManager
+## Shortcuts
 
- * We don't have a short manager for GTK 4 yet. We will want an accessory object for IdeApplication or 
similar. Alternatively, the workspace should monitor the IdeRunManager for changes and add/remove shortcuts.
+We still need a Shortcuts manager and a way to define shortcuts, especially by users.
+My plan so far is to have an IdeShortcut which is has a few things in it:
+
+ * "action" or "command" property of what to activate
+ * "params" which is the GVariant parameters
+ * "when" which is a simple set of rules we can apply if we can activate it
+   such as `inWorkspace(primary)` or `inPage(editor)` or `hasProject()`.
+ * A "phase" that allows changing bubble/capture semantics
+ * A list model to filter all of these out based on workspace status/focus/etc
+ * A custom GtkShortcutController to apply these rules from the model
+
+## Editor Search
+
+This still hasn't been brought over because it needs a lot of changes for
+GTK 4. However, most of that was already done on GNOME Text Editor. We also
+probably want to change the layout based on updated designs from Allan.
+
+## Global Search
+
+I'm trying to wait for GtkListView with sections, but perhaps we can skip
+that and add sections later. The search engine plumbing is there, along with
+the dummy popover window.
+
+I also want to add a secondary popover that allows us to animate in a display
+of file content for the selected entry with highlighting.
+
+## Find Other File
+
+This supports F4 for switching between source/header/ui files and what not.
+It used to build on the global search, and perhaps we would still want to
+do that in some sort of way.
+
+## Configuration Editing
+
+This is still needed in the "Configure Project" window although I'm not sure
+yet how we want to see that displayed. Should it be a list of additional pages?
+
+Should they be sub-pages like languages are?
+
+## Multiple Cursors
+
+This needs to be ported to GTK 4 too, and merged into IdeSourceView again.
+I don't like the code much and I'm not sure I want to maintain it, as it's a
+giant pile of hacks that don't guarantee correctness.
+
+## Beautifier
+
+Ideally, just rewrite this plugin. It doesn't need the level of complication
+it needed when it was originally written as Builder has less machinery then.
+
+## Color Picker
+
+This probably can use a lot of simplification from a rewrite as well.
+
+## Command Bar
+
+This will go away, and become part of the global search.
+
+## Glade
+
+This will go away, and instead use Drafting.
+
+## GVls
+
+Not sure what is needed here, but it should definitely be ported to
+IdeLspService at minimum. We don't enable it in our builds anyway.
+
+## Editor
+
+This can be deleted once `editorui` is finished.
+
+## Emacs
+
+This can probably be deleted. We are unlikely to support emacs like we did
+previously as it didn't get much usage and was often just broken.
+
+## Devhelp
+
+This needs to only use books and drop any sort of use of it's widgetry.
+
+## Python Pack
+
+Port the indenter to GtkSourceIndenter, try to merge upstream in GtkSourceView.
+
+## C Pack
+
+Also port the indenter, and merge it upstream as well. This one is nasty, and
+could surely use a large rewrite.
+
+## Vala Pack
+
+Port the indenter, upstream to GSV
+
+## Shell Command
+
+The preferences is the part here that will need work as well as integrating
+with the updated shortcut controller work.
+
+## Sublime
+
+Port to the new shortcuts engine. Can probably become a .json file descripting
+all the keybindings in our new syntax.
+
+## Sysprof
+
+Port to use IdePage and get rid of the whole surface madness.
 
-## IdeSurface
 
- * We should rename this to IdeWorkspaceContent as it fits better with the `content` metaphor 
AdwApplicationWindow.
- * Alternatively, we can probably just drop IdeSurface altogether. Instead, project properties could either 
be shown in a page or with a new dialog like we do for preferences (or a workspace window so it gets access 
to IdeContext).
