Ideas for enhanced user experience and workflow in Adobe Photoshop

Hey there, I am a windows user and I would like to utter some things that I mind in Photoshop respectively features that I would welcome in a future version of Photoshop:

1.) The gradient-tool is great but why don´t you just display it as a line, with 2 dots at the end, that stays on the screen so you can adjust the gradient more comfortable. In my opinion it is laborious to re-draw the gradient over and over again just to make a tiny change because the line disappears every time.

2.) My workflow could be accelerated if I would dispose over the opportunity to press the mouse wheel and drag in order to move / execute the same function as the hand-tool (letter H) respectively space bar + left mouse key. 

3.) Press "U" and draw a shape. If you want to give the shape a border it will be set to a weird spiky style border by default. Why is that and who does not change it to the first option in the drop down menu (which is the normal contour)? Wouldn´t it be smarter to set the contour to a line style by default that 99% of the people want when adding a contour to a shape the way I described right now?

4.) Talking about the path-tool (press "P"): Draw a point and curve it. After you drew a curved point it is impossible to continue with a straight line so you have to hold the "alt"-key and press on the last point in order to be able to continue with a straight line. That is super time-consuming and annoying in my opinion. Can you set it to default that you automatically continue with a straight line regardless of the circumstance if the previous line was curved or not?

5.) Why not integrating "Adobe Firefly" or at least a "text to image AI" directly into Ps?

(B1. Press "T" and add a text. In the horizontal menu bar over your project frame you can set a text smoothing option f.e. sharp or windows LCD. I can´t find reliable information which option has the highest possible quality when working on an image that is destined for a social media post / YT-thumbnail. Or is the highest resolution option already set by default?)

(B2. What I don´t understand but what is surely immutable: Why were not the keyboard shortcuts assigned uniformly among the programs of the CC? "Ctrl+J" = duplicate a layer in PS, but in AE duplicating a layer requires another keyboard shortcut. If there were a program in which a shortcut wouldn´t make sense the key could have stayed unassigned f.e. "M" for "muting the audio in Audition" does not make sense in Ps (because there is no audio in Ps), so it stays unassigned but in Premiere Pro "M" would also be the shortcut for muting audio. Does this concept sound comprehensible to you?)

This would have facilitated the prodecure of learning / becoming familiar with the handling of new Adobe programs (kind of a linked shortcut feature how I would label it).
