Alt click on a node connection automatically disconnect it from the other nodes. And there is some nodes which can be easily summoned by pressing a key and clicking at the same time. Like B+click will place a branch, and S+click a sequence.
If you're willing to compile it, Aseprite is a great option as well.

William Vaughan has shared a “tool” he started using back in the mid 90’s and haven’t stopped since. Basically it’s a simple, but extremely powerful life safer called a Change Authorization Form. The form allows you to document any changes the client has requested that fall outside of the original contract that both parties have agreed to and signed.
As long as it’s clearly defined, any changes that fall outside of the contract should be greeted with a change authorization form. Even if you don’t plan on charging the client for the changes, it’s a good idea to formally document them so you can track any and all changes that may come up during production. It’s a great resource that has saved my butt several times when a client asks “Why did you change that?” or “Who approved this change?” The form will clearly show why changes were made, who approved them, and how it has affected the project’s time and budget.
Key elements you’ll want to include in the form:
- Name of Client
- Name of Artist/Studio producing the work
- Who requested the change
- Date the request was submitted
- Description of change
- Reason for Change
- Estimated costs associated with change (Time/Money)
- Impact on total budget and schedule
- If approved, who approved the change
You can also edit your form and remove unnecessary details to fit what works best for you or your studio.
