I find the path to changing the steps a bit lenghty, mostly when in the process of creating/improving a new build:

1. I am now in the build results and want to change something in the steps
2. I click Files in the sidebar
3. I click on the .onedev-buildspec.yml line
4. I click on the tiny pencil icon: it is on the right, which is unusual as most of the time it stays on the left
5. I click on the three dots of the step I want to change and proceed with changes
6. I save the step
7. I am back to the build
8. I save the build clicking on the tiny Save icon
9. I have to commit the changes
10. I can relaunch the build with the blcak button

I have the feeling that process should be streamlined by declaring an "Editing Mode" (a checkbox) which would automatize most of the steps:

1. I check the Editing Mode checkbox: an additional line appears in the sidebar that brings me straight to the .onedev-buildspec.yml file, in editing
2. I click on each step to modify it
3. I can click outside of the Step window and it is saved by default (but there is still a Save and a Cancel button I may use)
4. I save the .onedev-buildspec.yml file and it is automatically committed
5. I can execute the build anew
