when auto scheduling in gantt, start and finish dates are not synced with Start Date and End Date of the issue and later when generating reports, we cant have a realistic report

XRay instroduced a Test Repository in v3. Now every XRay test has a field 'Repository Path' looking like: '/Test Repository/Release 1/Phase 1/AAA/'.

However, the Structure view is still better than XRay repository. It would be great to be able to import XRay tests recreating the same folder structure as in the XRay test repository automatically. So that users can use both XRay test repository AND Structure.

Allow the ability to add hash marks to the parent time bar in Gantt based on child dates. This would allow to see milestones without cluttering the view with multiple child issues.

As a project planner I need to be able to define a dependency with an offset.
Example: Task 5 can start 3 days after Task 4 starts. I would define that as a Start-to-start dependency from Task 5 on Task 4 with a +3 day offset.

A regular express text function would be very useful to extract content from a Text field into a column.

For example, if a Description field has:

Name: Value
Name1: Value2

I can write a regex formula to extract out the value for Name: into a Column.

I know it's not likely that you can interface with every other add-on that structure customers might also use, but selfishly, I would love to be able to view all test cases associated with an issue under that issue (similar to Extend with linked issue).

Add a count of the number of comments.

This idea is a to provide a way to display only (or to hide) some fixVersion instead off all of them when we use the grouping feature. If it is possible to choose the storing order (asc, dsc) it would be awesome !

These fields are of extreme importance for time management throughout the project.

I'd like to see my dates roll up the hierarchy so that I can see higher level estimates as they roll up. For example, if I have a folder for a project and I have a number of tasks underneath, I'd like to see the latest due date in the project, or the earliest start date.

As a gantt user, I would like to get my the release date of my versions automatically projected as milestones on the timeline, so that when I bind a task to it, it automatically update the fix version/s field.

To provide a backlog forecast it is essential to show what content could be done within a certain time or time budget. If we configure the budget in a top level issues custom field, structure could SUM not only by level, but also the contents of the current list of elements (eg. by priority) and a formula could show from which element the budget is overspent.

Our users will customize their view, setting the column widths in a way that allows them to best see the data in the view. While Structure does a great job of preserving this, in their session, there is no way to save the column widths, either in a saved view or in the "perspective view", from the Share button. Our users would like to share these adjusted column widths with other members of their team.

Automation + Grouping on Multi-Cascading Select fields is a top-notch function that allows users to efficiently organize complex datasets, but are functionally limited to deeper organizations.

If I start using the Jira-system 2-tiered multi-cascading select field in Structure for my issues, but then decide I need to switch to a 3-tiered mutli-cascading select to model my data, I sacrifice the functionality of Structure for the flexibility of another add-on.

Including support in Structure for n+ Multi-Cascading Selects, e.g iDalko's multi-select field (using MySQL), would help users like myself fully harness the capabilities of automated issue structures

I would suggest you to resort exclusively to the AUI objects for your interface instead of your custom ones that clearly gives the impression that you are exiting the Jira world to step into another one.
I think you user would deserve a smoother user experience, with the same kind of buttons, icons, tables to which they are already used to. I'm especially talking about the transformation/filters features that should be improved in that direction to my mind. Thanks for you great achievement!

Budgets are often not added as issues. Structure could add value by allowing some limited amount of named custom fields on structure-folders (like notes, but some more). They would bind to a structure and could be accessed from formula columns.

The Structure 4.5 documentation doesn't identify how to create a NEW Formula Column.
https://wiki.almworks.com/display/structure/Formula+Column

Step 1 should identify how to add a new field, not how to write the formula.
