The current popup window that suggests existing hashtags is relatively small if a large list of hashtags exists.
If I have a long list of existing tags, I have to scroll a lot further down thru the popup window due to the current window size. A larger window would allow for more tags to be viewed while scrolling
Proposed solution
Make the default popup window larger, or better yet, make it resizable by the user and with the window retaining resized position going forward
Current workaround (optional)
No current workaround
