I have made an app that is used for searching for a file and then running it. It is still a work in progress, but I think it is useable and useful in its current state.
You can search and choose what to open while the results are coming in, which can be useful if you are searching a lot of files. You can use the arrow keys to choose the file you want or the enter number of the file you want to open and press enter.
Feel free to open pull requests and raise issues. It is a work in progress and I would appreciate all the help I can get.
Long term I am thinking about making it a GUI app, and also thinking about prioritizing which folders to search in what order depending on you history of using the app.
What do you think?
