thanks in advance
i have two questions

at first, on gantt chart, there's no sorting feature.
for most cases it doesn't matter.
but for some cases like when start date is changed, it's hard to check the gantt.
it doesn't look like stairs or waterfalls anymore, but zigzag looking.
is there any method to sort the gantt that way?
if not, please add some features or modify to be sorted asc with start date of issues even among subtasks.

second, i have no idea how to upload image at home page.
yeah i know there exist tags for pictures.
but as distinct from wiki feature or image feature on issue,
there's no way to upload image directly to home page.
does it exist?
if not, give me some good ideas or please add some features.
