[Feature] Optimize user experience of FastPR

[frank-zsy]

Description

Enhance the user experience of the FastPR feature:

• When a user selects a portion of text with their mouse, move the button to launch the editor near the selected text to facilitate quick access to the editor.
• When a user opens the editor within the document, approximately estimate the current position in the document based on the scrollbar's position, and align the Markdown editor to that approximate location. This alignment does not need to be accurate.

• When a user selects a portion of text with their mouse, move the button to launch the editor near the selected text to facilitate quick access to the editor.

Is this expected to achieve a similar effect, or does it mean something else.

[frank-zsy]

Yes, this is exactly what I mean~

For the second point, how to adjust the position of the navigation bar for the content in the stackdit. There is no similar functionality in the stackdit API.
If scrolling through stackdit to control page sliding, there is still a cross domain issue.

I just assume this will be quite helpful for long document but I am not sure this is feasible or not. I need do some experiment first and I think this may involve some hacking into StackEdit source code.

[frank-zsy]

I can not find any method to do this neither so I opened an issue on StackEdit GitHub, but don't count on it because the project is not active for a long time. I think we can hold the issue and wait for a response. benweet/stackedit#1856

One more thing to add is the initial position of the button. Is the initial position reflected in the configuration file or elsewhere? Add a return item in the configuration file that represents several common positions such as top, bottom, left, right, bottom right, top right, etc

[frank-zsy]

@wangyantong2000 Yes, the initial button position is very important, it should be in the config file. We can use common positions instead of x, y position numbers, this will be quite friendly for config. This could be a new issue.
