Customization like, changing the default "Read more" text or adding an image instead of read more link or the fix for the new option which takes you to that particular page obviously, but it jumps to the line after the "jump-break" option has been applied, when clicked. If you don't want this to happen and think that it disturbs you and your readers as well, then edit the code and fix this by the simple tutorial.Go to Design > Edit HTML tab, and then click the "Expand Widget Templates" check-box.
Find:
<b:if cond='data:post.hasJumpLink'>
<div class='jump-link'>
<a expr:href='data:post.url + "#more"' expr:title='data:post.title'><data:post.jumpText/></a>
</div>
</b:if>
And delete:
+ "#more"
