Feature request: pixel scrolling on supported trackpads, as well as improving the current scroll implementation regardless

Submitted by FastScroller on March 25, 2020 - 1:03am

Modern laptops, perhaps as a response to Apple's magic trackpads, implement "pixel scrolling". In the past, Windows would scroll 3 lines at a time. This was best suited towards mice, where scroll wheels have notches and each notch would scroll 3 lines. Trackpads in Windwows in the past scrolled 1 line at a time, still very jolty. With the advent of multitouch capable trackpads, pixel scrolling means Windows and supported apps will scroll a pixel at a time. The best way to describe this is the scrolling experience on a smartphone.

Feature request: allow ctrl+backspace to delete whole words in the portableapps menu's app search

Submitted by FastScroller on March 25, 2020 - 12:58am

Everywhere in Windows, backspace allows you to delete one character to the left of cursor at a time. However, in some parts of the OS, Ctrl+Backspace is also supported. This allows the entire word to the left of the cursor to be deleted. For example, the Run dialog (Win+R) or Windows 10's start menu search. Some areas this has not been implemented, such as while renaming a folder in explorer. In such cases, explorer interprets it as some kind of unicode character and will insert a square box  instead.

Write default data with environment substitutions?

Submitted by DrDinosaur on February 17, 2020 - 6:24am

I need to write this XML file on first launch and every launch after:
https://pastebin.com/5U9fsaF1

This doesn't work first launch, as defaultdata doesn't use environment substitutions.

Whats the best way to do this? Just remove all the root URLs and home path then write in the launcher?
Im going to have to write with the launcher anyway to update paths at startup.

Thanks.
