Add option for scrollbar up/down/left/right arrows to move page in adjustable speed with mouse
Importance: Major
Description: it is not possible to move page with mouse in precise steps. In Linux arrows can be added to the Gnome GTK 2 or 3 theme but they do not appear in Sublime 3 but in every other app (file manager, terminal, firefox…).
See my original topic: Adding Arrows to Scroolbar for up down
Confirm before deleting files in the sidebar, this has irked me for so long now.
Multiple selection of packages to be updated
This is regarding Package Control, but since Will is now part of the Sublime Text theme, I’m going to assume that some future version of Sublime Text might eventually ship with or integrate Package Control.
Currently, one can choose between “Upgrade/Overwrite All Packages” and “Upgrade Package” and then select a single package to be updated. For the latter, it would be nice to be able to select multiple packages (e.g. using Space key) and then upgrade all selected packages. While I can’t think of a practical example, multi-selections might be useful for other dialogs as well.

Style console output
I often use the console and the overview is currently very limited. I’d like to propose options to style or colorize the console output.
Needless to say, that these should be optional.
Importance: Biased 
It would be nice if each menu entry was also available in the search bow (ctrl+shift+p).
I’m thinking for example to “Exit”, changing line endings, Open folder, Open recent, Record macro, …
There are a lot of commands that I don’t use very often and that I struggle to remember shortcuts and/or positions in the Menu.
Imo, every action listed in the menu should be exposed to the command palette as well. That includes packages and their “open Settings” commands. Sadly, only few packages do this.
Configuring sublimes settings via the command palette (much like a plugin provides support for) would be a good one to have native support for as it feels much more intuitive and in most cases faster.
Customized title bar, and Menu Bar with background-color & font-color
Importance: Minor
Description: ST like a very beautiful girl but wearing a very old hat.No matter how beautiful clothes can not save the regret caused by the hat.
And, if themes can modify the Menu Bar’s background-color & font-color,it seems to be more harmonious and beautiful.
If the title bar and menu bar can be combined together, it will be better.

Fix the bugs of UI Localization (2)
Importance: Major
Description: The caption of toggle menus…
Whether it can be like this:
“caption”: “the caption to be show||the caption to be hide”,
When ST read the “||” contained in the caption, to deal with it as a toggle menu.
Fix the bugs of UI Localization (3)

Description: There’s no setting used to localize these parts of the picture:
By modifying the EXE file, these can be localized. But this is not good. At least, it’s too tired to keep up with the pace of the upgrade.
Strengthen the sidebar
Importance: Major
Description: Show the headers tree of MD file in the sidebar, and click the header to jump to the corresponding location. This is better than Ctrl+R (goto symbol).
Support for sidebar customizations like the color-coded system for git integration in Atom:
Add the possibility to change the background color of match_selection, right now is only possible to change the border color.
It would be great to be able to hide tabs per pane. This is useful if you have a REPL (e.g. SublimeREPL) with a single tab below your main pane and don’t want to waste vertical space for that one tab.
I would like to see an option to make highlight line only apply to wrapped line when editing wrapped text, rather than the entire line, if that makes sense. The highlight line feature is useful for keeping track of where the cursor is, but it is currently not much use for editing long paragraphs.
My suggestion is to change an existing behaviour when the Input Panel is closed when an output panel opens.
Not sure if this falls into API or interface, but I would like to have the option access arbitrary settings from build systems. Build systems are currently quite inflexible; the shipped build system is rarely applicable on all platforms in all situations. Specifically, I would like to be able to add settings so that users can set their own executables and flags, without having to recreate the whole build system. Variables would allow this:
Build system:
{
"cmd": ["${fortran_gfortran_binary:gfortran}", ${fortran_gfortran_flags:[]}, "${file}"],
}
User’s settings file:
{
"fortran_gfortran_binary": "/usr/local/bin/gfortran",
"fortran_gfortran_flags": ["-O3", "-fdefault-real-8", "-etc"]
}
In the above example, it would be great if the variables could be lists, as demonstrated.
