[2021] Steam client features feedback

As one of the seemingly few people who actually use the Steam client, I feel it's important to raise feedback on the features and I don't know where else to put this feedback than here.

1. Opening the side bar alters (reduces) the playable area of the window, the closing it again expands the playable area again. This feels wrong and counter-intuitive when used, it's more natural that the side bar should open to the right and expand the client window rather than altering the actual game area of the window.

2. The above behaviour regresses further for certain client sizes. For example if you set the size using the command "::setwindowsize 1000 650" then open and close the XP tracker bar, the client does not return it it's original size, instead it retains the size of the reduced playable area from when the side bar was opened.

3. Object highlighting doesn't work in the PoH. GIF example: https://imgur.com/a/iK2yzFA
4. Enemy HP bars are inconsistently working for some enemies e.g. Hydra - sometimes it's there and sometimes it's not (maybe something to do with switching phases?). Not been there for a couple of weeks so this may have been fixed already
5. Marked tiles do not persist in some areas e.g. Catacombs of Kourend. GIF example: https://imgur.com/a/0hUk68z

Most features introduced are working great and the client is getting better with every update - not quite enough to get me using it 100% of the time yet but moving in the right direction
