I am using it right now. It works very well, also context aware so that it shows different stuff depending on what you are doing like in the debugger you will continue, next etc.
They already do, in the 2018.2 EAP there is support for touchbar. Since it's already in RC state I think the stable version will be out in a couple of weeks.
Project I am working on now is made only with Chrome/Firefox/Safari in mind, but the audience is mostly 20-25year old hipstery people IE share is less than 5% so we decided to not bother with support for them and just show a banner suggesting modern browser. But it's unusual to not support IE at all, usually I support 9+ if you want lower that will be extra fee.
Yeah but favicon appears next to the bookmarked page's title in browsers. If there's no favicon you can't say which page the bookmark leads to after deleting the whole title to save space :-)
IMO, I dont really care about it that much. You will probably want to change laptop after 2 or 3 years anyway, during this time battery degradation should not be a massive issue.
Exactly, that's my method as well. Although I have to say it's not so much a necessity rather than a preference for new and shiny. Hardware is so powerful nowadays.
There is a great plugin for sublime for that. It is called simple tasks if I recall correctly (Always forget the name of this plug in because of it generic name) It allows to still be using plain txt file but adds nice shortcuts and allows to make checkboxes.
