Enhancements for Code Explorer panel (gentle bump)

[pjj]

Let me come back to the features I asked for some time ago, regarding Code Explorer:

1. When there are no entries (I mean: Module, Todo etc.) for a newly opened file, you never know if and when they appear; this is very whimsical: sometimes they do show up without any user interaction, sometime they appear only after an edit (but was the edit the trigger? no idea).

However, if I open a *.php file for which no entries are present, and then change the highlighter to e.g. CSS, they appear immediately (!). I guess it's a bug rather feature request for showing a spinner, then. Nåja...

2. Please make it possible to set one of these entries as a default for all the files: since I'm interested in TODOs more than in Module or Favorites (which I hardly use), after switching to another tab I need to click on TODO entry again.

If I set e.g. TODO as a current entry for file a.php and go to b.php, for the second file default entry is Module (being the first on the list), so I need to click on it to show my TODOs there. When I come back to a.php, current entry is TODO, which is great, but after a single edit it switches again to Module

3. Please display bookmark's number for numbered bookmarks in Bookmarks section.

I want my numbered bookmarks to be consecutive, so sometimes I add random numbered bookmark (e.g. "3") in the middle of the code, so I can add another one(s) above it, with smaller number(s). So I go to another place in code to add my new desired bookmark number... wait, was it "3" or "2"? Can I use "2" here? Let's add it as "9", go down to find out if it was "3" or "2"... OK, it was "3", so now I come back to "9" to change it's number to "2". Well, yeah but the struggle is all too real, and displaying those numbers in Code Explorer would ease my pain.
