How to fit to view custom masked block permanently?

I was created custom library, it works, but one thing is quite annoying. When i open my library and unlock it, then go to 'look under mask', it opens out of view:

I tried to fit it using the "fit to view" option, then save it, but after reopening, nothing changes.

How to save the default view permanently?

Okay, I made it. The problem was that I wasn't moving elements actually, but background. So if someone will face a similar problem, I recommend do not moving background after open subsystem/mask, because it will come back to its zero position after reopen. Just select blocks, then drag and drop it.

Select All, move all the blocks to the top-left cornor as close as possible.

That works only at current session, after close->open mylib.slx problem occurs again

[Fangjun Jiang]

You need to save mylib.slx

I save it. And check the save: i add other blocks, and save. then, after reopen, changes like new blocks and connection modifications are saved, but view remain old.

Every block has a property called "Position". It is in relevant to the top-left corner. Once you save the model, try to reload the library or re-start MATLAB.

Thank you for your help, you helped me find a solution.

By the way, it's quite confusing that the position of the blocks refers to a corner that you can't see, and you don't know where it is if you moved the background. It would be nice if the simulink had a "restore background to the starting position" button, or there could be a marker that the coordinate system starts there.
