Awesome Custom Fields for Jira Cloud

In my professional environment (construction), scheduling processes in calendar weeks is very common and has been proven in practice. Almost every construction project is carried out in calendar weeks rather than days. Would it be possible to implement this? In my opinion, this would be a unique selling point, as I don't know of any other app that offers this feature. Ideally, it would be configurable to display calendar weeks, but internally use dd/mm/yyyy with evaluation in JQL as calendar weeks. Thank you.

Custom Field Country - dropdown single and multiple choice. When you choose this custom field, comes a list with all countries with the flags (the same as phone validation)

We would like to be able to have a "line item" field with an item description, quantity and cost field on one line. Currently I handle this separately with individual fields and it's a mess when working with more than one line item

I'm using a cascading field, and I need to set the value in a loooot of issues. The workflow would be much smoother, if I clicked the field in the issue, and then the cursor / focus would be in the field already, so I can start typing right away. Instead, I need another click to put the cursor into the selection field.

Currently when using the customfields of "Awesome Custom Fields" the values are shown in the middle of the screen. Is it possible to relocate them more to the left like a normal field? This is basically for all customfields the same.

It would be great to get a new fieldtype for numbers which supports conditional formatting based on the value of the Input. Similar to the "Price Tag" just without the currency tag.

Need more colors for labels, not enough

Our agents are using some fields inside the JSM. We need to show some of them to user in read-only format without adding the new ones. Btw, we are using simple select and short text which are missing in the plugin.

I'm looking for a way to have a text field that searches previously entered text to match off of to prevent duplicate data when possible. This would be similar to how the Jira Component field works.

I have al large list with context fields options. I have to enter them by hand. I need a possibility to upload or paste them on edit options. Maybe this is possible with your custom fields solution?
