The feature is very versatile and it has good support for Chinese and network proxies. It has a good design to support a good plugin ecosystem. I really wanted to love it. However, it doesn't satisfy R1 and R2.
R1: It does have
Win+R support for open/close but limited to shell commands. The shortcut to open/close to search is
Alt+Space. And unfortunately, the key combination can't be changed to anyone that includes the
R2: It can be configured to use a folder that contains links to applications to simulate keywords, but they won't always show at the top.
Also, another downside is the development is not active recently. From GitHub issues, there are lots of seemly same bug reports. I can't find a community to ask questions.
